Chemical Properties of Matter

Chemical properties are any of the properties of matter that may only be observed and measured by performing a chemical change or chemical reaction. Chemical properties cannot be determined by touching or viewing a sample; the structure of the sample must be altered for the chemical properties to become apparent. Examples of Chemical Properties Here are some examples of chemical properties. Reactivity with other chemicalsToxicityCoordination numberFlammabilityEnthalpy of formationHeat of combustionOxidation statesChemical stabilityTypes of chemical bonds that will formMore examples Uses of Chemical Properties Scientists use chemical properties to predict whether a sample will participate in a chemical reaction. Chemical properties may be used to classify compounds and find applications for them. Understanding a materials chemical properties helps in its purification, separation from other chemicals or in identification in an unknown sample. Chemical Properties Versus Physical Properties While a chemical property is only revealed by the behavior of a substance in a chemical reaction, a physical property may be observed and measured without changing the composition of a sample. Physical properties include color, pressure, length, and concentration.

Stride Gum Free Essays

Is It Ridiculously Long Lasting? In the recent Stride commercial, Shaun White endorses their new Whitemint flavored gum. The advertisement’s main purpose is to promote the gum by creating an ironic situation that grasps the audience’s attention with a humorous tone. Without stressing the product so heavily, they provide a less demanding approach for the audience to buy their product. We will write a custom essay sample on Stride Gum or any similar topic only for you Order Now The advertisement promotes the gum as ridiculously long lasting. Although, throughout the commercial, the marketer’s debate over solutions for the consumers to chew another piece. By the end of the commercial they come up with the solution for consumers to either â€Å"Spit it out. or Yeti will find you. † Stride Gum Inc. uses irony, social appeals, and tropes to lure the audience. The ironic situation in the Stride Gum commercial is how it is an advertisement within an advertisement. Obviously an advertisement’s purpose is to promote a specific product. But in this advertisement, it shows the marketing professionals for Stride Gum deciding on ways to promote their product. It is ironic to see a commercial that is about their company making their commercial. Another ironic appeal is Stride Gum’s use of a yeti. At the end of the commercial, Shaun White comes up with an idea to get the consumers to chew another piece and quickly gets on his phone. Suddenly, a giant yeti comes barging in the meeting room and punches the head-marketing executive in the gut, forcing his gum to shoot out of his mouth. The audience clearly knows a yeti would never come force their gum out by punching them in the stomach, let alone even encountering a yeti. This sets a humorous tone for the audience to relate to which increases their interest for the product. Another tool Stride Gum incorporates is their usage of a social appeal. In their commercial, Stride features Olympic gold medalist Shaun White. Just this year Shaun White was named the second most powerful athlete behind Peyton Manning. Not only is White a tremendous snowboarder and skateboarder, he has become a celebrity and role model for the youth culture. Stride purposely uses Shaun White to target the youth audience because of his friendly face, personality, athletic ability, and popularity. Once the youth audience sees him on TV, they instantly feel a connection that the older generation cannot relate to. Being a popular hit for sports and role modeling for the fans, White makes Stride Gum a sure way to instant marketability. Lastly, Stride Gum uses the appeal through tropes to capture the audience. The first trope used for the Whitemint flavored gum commercial is, â€Å"The ridiculously long lasting gum. † When they first advertise this gum as long lasting, Stride’s main purpose is to suede the audience in believing their gum lasts longer than other competing products. But throughout the commercial the main concern for the marketers changes into getting the consumer to chew another piece. The change is ironic to see because at the beginning Stride really wants the audience to believe their gum is ridiculously long lasting. But by the end of the commercial, they act like the viewers have already believed their long lasting flavor proposal. This then puts the stress on the idea that the marketers are trying to find a way to get the consumers to stop chewing it and get another piece. By using these two different tropes, it represents Stride as being confident that their gum is long lasting, and its so long lasting they have to find a way for people to spit it out and chew another piece. By the end of the commercial the slogans change from â€Å"the ridiculously long lasting gum† to â€Å"spit it out, or Yeti will find you. † Stride purposely changes the tropes because they want the audience to believe that the Stride marketers have perfected long lasting gum. They now want the viewers to believe their Whitemint gum is so long lasting that they are facing the issue of getting the consumers to chew another piece. With the use of transforming tropes, social, and ironic appeals, Stride Gum Inc. attracts the audience’s interest and attention. Shaun White and the yeti implement a humorous tone that coincides with the ironic situation that appeals to the youth culture. Also, switching up the tropes sways the viewers to fully believe Stride Gum’s advertisement due to the confidence displayed by Stride in the commercial. By applying multiple appeals into their commercial, Stride Whitemint flavored gum is advertised effectively to sway the younger generation’s interest to consume their product.

Maglev Train for Electricity and Magnetism- myassignmenthelp

Question: Discuss about theMaglev Train for Electricity and Magnetism. Answer: Outline Structure Maglev is an abbreviation for the magnetic levitation, which is a process and transportation method where it describes the movement of a suspended object without any other support but through the use of magnetic forces. In transport, maglev train has been able to embrace this technology and ensuring that the vessels are not in contact with the ground (Lecture, 2002). The magnetic forces in this technology are used in order to counteract the effects, which are brought about, by the gravitational acceleration or any other accelerations which may bring the object movement. In the maglev, the major key subjects, which are able to get involved include the lifting forces and the stability measures (Mestel, 2006). The lifting forces in this mechanism are able to provide the upward force, which is used to counteract the gravitational force or other downward forces. Moreover, the stability issue is able to ensure that the whole system do not slid or flip out of the configuration. In these tra ins, the magnet is able to provide the lifting force and the repulsion force which is required for the vessel to move. The main aim of this technology in the trains is to ensure that the frictional forces is reduced to zero and therefore enhancing the increase of the speed movement (STR, 2003). Moreover, through this technology, the maglev trains are able to move smoothly and quietly as compared to the mass transit systems and trains. In addition, another key area, which this technology is to focus on the energy consumption and the technology, enhances the energy efficiency. In terms of the trains speed, the maglev trains are able to hold the highest speed of the trains. Laws and Theories The maglev technology in the train is able to use the forces of attraction of the magnets to enhance the movement of the trains. The maglev rain is able to apply the magnetic forces to ensure that it is able to maintain its speed and stability. The maglev technology ensures that the train is suspended above another object (STR, 2003). The laws of magnetic attraction and reputation are abler to apply in ensuring that the technology is able to achieve its objectives. Moreover, the interaction of the gravitational forces and the magnetic forces are other key rules which is applied on this technology. The maglev train has to be maintained on the suspended position and ensure that it is able to move at that position. The magnetic forces have to control the downward pull of the gravitational forces (Mestel, 2006). The repulsion between the magnetic field and diamagnetic substance is able to enhance the ole of this technology. Moreover, the attraction between the unlike poles of the magnet must be maintained to ensure that the train does not move much higher. This balance is in maintaining the position and stability of the maglev train. Through the electromagnetic attraction, the sensors are able to enhance the reduction of the frictional force since the train is suspended (Thompson, 2013). Moreover, the levitation force is another rule which the technology is able to embrace. This ensures that the train is able to attain it maximum speed and able to move forward. Lastly, the linear synchronous motor (LSM) is able to ensure that the maglev technology is able to move and attain the required speed. Other technology and rules in this technology is the Linear Induction Motor (LIM) and reluctance motor. Description of the Way Laws and Theories Work The device is able to ensure constant level of the train through the magnetic force attraction and repulsion. In addition, one of the force, which is critical in the maglev train, is the levitating force (Lecture, 2002). This force ensures that the train is able to move forward and attain the specified speed of design. There are three different levitating systems which could be applied on this technology. These include EDS system, EMS system and INDUCTRACK systems (Mestel, 2006). The eddy currents are able to play a key role in ensuring that the levitation of the maglev train is achieved. At different speeds, the induction poles are able to behave differently. The EDS is usually in both the train and the rail, which is able to offer the repulsive force leading to navigation. The EMS, which is a shirt form of the magnetic suspension, helps to employ the magnetic attractions. Discussion of Issues The speed issues have been arising each time. The train is modified to increase the speed limits with japan holding the fastest maglev train followed by china and formula I racing car. The increase of the speed is able to affect the stability, therefore needing proper consideration. Stability is another key issue which is raised (Thompson, 2013). The speed is able to lower the COG and therefore placing the risk of train failing. A small displacement will be able to change the stability equilibrium which may lead to accidents. The increase in distance is able to lower the strength of magnetic attractions which is a key issue in the maglev train. The strength of the magnet is able to the stability and the security of the train. This is a key issue which is required in the application to ensure that the train is safer and able to maintain the safety requirements. Impact of Maglev Train The achievement of high transportation speed is one of the positive impact, which the maglev train has been able to have. The high acceleration motors are usually used top, enhance the linear induction design of the maglev train. In addition, efficiency is another key impact which this technology is able to embrace (Rote, and Yigang, 2002). The same magnet, which is used on board on the train to supply the lifting force, can be used to guide or even offer separating guidance of the magnets. This technology is able to ensure that high speed is achieved at the most economical measure. This is a key impact, which is able to enhance the speed of the train. The train speed is able to enhance the movement between different points. References Ignorance = Maglev = Bliss For 150 years scientists believed that stable magnetic levitation was impossible.

Jazz Music- The Roots Of Our Everyday Life Essays (667 words)

Jazz Music- The Roots Of Our Everyday Life What is Jazz? According to the dictionary, jazz is defined as, ?A kind of syncopated, highly rhythmic music originated by Southern blacks in the late 19th century? (?Jazz? 232). But, everyone should at least agree that jazz is the mother of all music, and is referred to as the only art form originating in the United States (?History 101? 2). America was home to immigrants from all over Europe and beyond who wished to build a new life, or just needed to escape from the old. These people, often thought of as second-class, brought their culture with them to America, expressed it musically, and changed the music world as we know it today. Most early jazz was played in small marching bands or by solo pianists. Besides ragtime and marches, the repertoire included hymns, spirituals, and blues. The bands played this music at picnics, weddings, parades, and funerals. Characteristically, the bands played hymns on the way to funerals and lively marches on the way back. Although blues and ragtime had arisen independently of jazz, and continued to exist alongside it, these genres influenced the style and forms of jazz and provided important vehicles for jazz improvisation. Around the turn of the 20th century, the earliest fully documented jazz style emerged, centered in New Orleans, Louisiana. This city is often called the ?cradle of jazz? (?History 101? 3). In this style, the trumpet carried the melody, the clarinet played showy countermelodies, and the trombone played rhythmic slides and sounded the root notes of chords or simple harmony. Below this basic trio, the tuba or string bass provided a bass line and drums the rhythmic accompaniment. New Orleans jazz was just the beginning of an entire sweep across the county. The first true virtuoso soloist of jazz was Louis Armstrong. He was a dazzling improviser, technically, emotionally, and intellectually. He changed the format of jazz by bringing the soloist to the forefront, and in his recording groups, the ?Hot Five? and the ?Hot Seven? (Porter 2), demonstrated that jazz improvisation could go far beyond simply ornamenting the melody. He became the first well known male jazz singer, and also set standards for all later jazz singers, by creating scat singing: singing meaningless syllables instead of words, not unlike instrumental improvisation. During the 1920s, large groups of jazz musicians began to play together, forming the big bands that became so popular in the 1930s and early 1940s, (the swing era). The development of the big band can be majorly credited to the achievement of Duke Ellington and his revolutionary song, ?It Don't Mean a Thing If It Ain't Got That Swing? (?Jazz Music? 54). This soon became the new word for music played with a happy, relaxed beat. A new style also started in the early 1940's when a group of musicians started experimenting with more complicated chord patterns and melodic ideas. This group included trumpeter Dizzy Gillespie, alto saxophonist Charlie Parker, and pianists Thelonious Monk and Bud Powell. This new approach became known as bebop, or bop. Most bop musicians had exceptional techniques that enabled them to play long, dazzling phrases with many notes. In the 1940's and 1950's, jazz began to lose its reputation as a ?lowdown? music, and gained acceptance among intellectuals and college students. Jazz concerts became popular. Duke Ellington and other big band leaders gave many concerts, and a group of improvising musicians made a series of nationwide tours called ?Jazz at the Philharmonic? (?Jazz Music? 56). Jazz music was revolutionary and is still changing and improving, even today. The music world today would not be the same without the influence of these amazing and breathtaking musicians.

Quotes from Dracula, Bram Stokers Horror Classic

Quotes from 'Dracula,' Bram Stoker's Horror Classic Bram Stokers Dracula is a classic vampire tale. First published in 1897, the novel was influenced by a history of vampire myths and stories, but Stoker shaped all those fragmented tales to create a literary legend (that was just the start of what we know and understand about vampires in current literature). Even though stories like Polidoris The Vampire and Le Fanus Carmilla already existed at the time when Dracula was first published, Stokers noveland his literary imaginationhelped to spawn a new dimension in horror literature. Here are a few quotes from Bram Stokers Dracula. Quotes from Dracula I read that every known superstition in the world is gathered into the horseshoe of the Carpathians, as if it were the centre of some sort of imaginative whirlpool; if so my stay may be very interesting.- Bram Stoker, Chapter 1, Dracula Notes: The novel is written in the style of a journal, written by Jonathan Harker. Already, the author is playing upon preconceptions and superstitions, and leading us to expect something interesting, although what that might mean is not immediately clear. How does superstition figure into our perception (and fear) of vampires? Was this a customary incident in the life of a solicitors clerk sent out to explain the purchase of a London estate to a foreigner?- Bram Stoker, Chapter 2, Dracula Notes: Jonathan Harker is an everyman, a simple clerk who goes out to do a job and finds himself in the midst of a very-unexpected experienceforeign to his understanding. Hes a stranger in a strange land. As the Count leaned over me and his hands touched me... a horrible feeling of nausea came over me, which, do what I would, I could not conceal.- Bram Stoker, Chapter 2, DraculaWhen the Count saw my face, his eyes blazed with a sort of demonaic fury, and he suddenly made a grab at my throat. I drew away, and his hand touched the string of beads which held the crucifix. It made an instant change in him, for the fury passed so quickly that I could hardly believe that it was ever there.- Bram Stoker, Chapter 2, DraculaThe fair girl went on her knees and bent over me, fairly gloating. There was a deliberate voluptuousness which was both thrilling and repulsive, and as she arched her neck she actually licked her lips like an animal... I could feel the soft, shivering touch of the lips on the super-sensitive skin of my throat, and the hard dents of two sharp teeth, just touching and pausing there.- Bram Stoker, Chapter 3, DraculaI bent over him, and tried to find any sign of life, but in va in.- Bram Stoker, Chapter 4, Dracula But, oh, Mina, I love him; I love him; I love him!- Bram Stoker, Chapter 5, DraculaOh Lucy, I cannot be angry with you, nor can I be angry with my friend whose happiness is yours; but I must only wait on hopeless and work. Work! work!- Bram Stoker, Chapter 6, DraculaThe man was simply fastened by his hands, tied one over the other, to a spoke of the wheel. Between the inner hand and the wood was a crucifix.- Bram Stoker, Chapter 7, Draculaa man, tall and thin, and ghastly pale... I crept behind It, and gave It my knife; but the knife went through It, empty as the air.- Bram Stoker, Chapter 7, Draculathere, on our favourite seat, the silver light of the moon struck a half-reclining figure, snowy white... something dark stood behind the seat where the white figure shone, and bent over it. What it was, whether man or beast, I could not tell.- Bram Stoker, Chapter 8, DraculaBetween me and the moonlight flitted a great bat, coming and going in great, whirling circles.- Bram Stoker, Chapte r 8, Dracula I dont want to talk to you: you dont count now; the Master is at hand.- Bram Stoker, Chapter 8, DraculaI am here to do Your bidding, Master. I am Your slave...- Bram Stoker, Chapter 8, Draculait will be for her sake, and I must not hesitate to ask, or you to act.- Bram Stoker, Chapter 9, DraculaAll over! all over! He has deserted me.- Bram Stoker, Chapter 9, DraculaThe whole bed would have been drenched to a scarlet with the blood the girl must have lost...- Bram Stoker, Chapter 10, DraculaNo man knows till he experiences it, what it is like to feel his own life-blood drawn away into the woman he loves.- Bram Stoker, Chapter 10, DraculaThe blood is the life!- Bram Stoker, Chapter 11, DraculaIf that were all, I would stop here where we are now, and let her fade away into peace...- Bram Stoker, Chapter 12, DraculaNot so! Alas! Not so. It is only the beginning!- Bram Stoker, Chapter 12, DraculaHe was very pale, and his eyes seemed bulging out as, half in terror and half in amazement, he gazed at a tall, thin man, with a beaky nose and black moustache and pointed beard...- Bram Stoker, Chapter 13, Dracula Mein Gott! Mein Gott! So soon! So soon!- Bram Stoker, Chapter 14, DraculaThey were made by Miss Lucy!- Bram Stoker, Chapter 14, DraculaIn trance she died, and in trance she is Un-Dead, too...

What Criteria might be used to Define a State as Liberal Democracy Essay

What Criteria might be used to Define a State as Liberal Democracy - Essay Example The liberal state can be explained as an opposition of the individual against the norms of custom, tradition, and religion (Barry et al 2001, p. 3). As a result, the liberal inherently distrusted the imposition of any authority over the individual and the forces of the marketplace. Democracy is a means by which members of a community could ensure equality while working to achieve common goals and aspirations. Liberal democracy can be defined as a political system in which the application of state power is curtailed in several specific ways. The first, most important constraint is the clear separatior if the private and the public realms. Any explicit attempt to merge the two is considered illegitimate. Liberal democracies are also political systems in which any application of political power must be sanctioned by law and a certain degree of equality before the law is accorded all citizens. Political power is subject to popular control through regular, open, and reasonably fair elections in which at least two parties compete for power. Finally, while there may not be a constitutional separation of secular and clerical authorities, the former has prevailed over the latter, at least in recent times. (Bell 2006, p. 123). The main criteria used to defined the state as liberal democracy are the rule of laws and supremacy of constitution, voting rights and equality of all citizens, civil liberties and minority rights, independent judiciary and parliamentary power, independent media and religious freedom, subordination of military to the state power and freedom and autonomy of movements and assassinations. The examples of liberal democracies are France and Austria, Jamaica and Poland. Following Plattner (2007, p. 41), the general will of the community could force men to be free. Far from seeking to defend the liberty of the individual from the power of the state, the essence of democratic thought is to capture and employ the power of the state to benefit the community as a whole. Phrased another way, if liberalism proclaims the primacy of the individual, democracy demands the subordination of the individual to the collective welfare of the whole. Liberal values are not, of course, the only desiderata. Th ere are ideals which others share, of unity, efficiency, order and security. In addition, all societies today, whether democratic or non-democratic, pursue the secular grail of economic growth, and democracy is likely to be judged not only by its merits but its performance. Some account, therefore, had to be taken of the relationship between political reform and economic freedom--a liberalization of markets and the spread of local wealth to match the dispersal of political power (Barry et al 2001, p. 43). Civil society corresponds to liberal democratic society in its political aspects and to the pluralistic society of voluntary associations and private corporations on the other. Civil society entails the freedom of contract and the market economy. The private ownership of property and the freedom of contract and the organization of the market economy around them, are necessary conditions for civility in society. Seen in the crudest terms, civility and the market seem to be antithetical to each other--one altruistic, the other egoistic, the one inclusive, the other exclusive--but in fact they are mutually dependent. The very anonymity of the market, its relative disregard for the primordial and personal, is a necessary condition of the extension of the collective self-consciousness to the inclusion of unknown and unseen persons (Bell 2006, p. 13). Political scandals in the modern world can be understood only by developing an appreciation for this ambiguity concerning the use of politic al power-an ambiguity

The Role of Total Quality Management in the National Health Service Essay - 1

The Role of Total Quality Management in the National Health Service - Essay Example The researcher of this essay states that in the last couple of decades, there has been an increasing interest in the application of quality management into healthcare organisations around the globe. It appears that the healthcare system, in general, have largely embraced total quality management. One of this organizations, that are aimed to improve themself is the National Health Service (NHS). It is stated that the drive for total quality management began early in the 1980s as a fall out of the Griffiths Report. Since then, and over the following years, ‘quality’ has become a buzz word in the NHS. This essay intends to look at this developing importance of total quality management in the healthcare sector. And using the NHS as a guide, this article reviews the critical elements of total quality management, the different factors that come to play in promoting these elements and how these can be better put to use to improve the overall quality of service delivery in the N HS. The next section of the essay attempts a detailed explanation of the term 'total quality management', to establish a background understanding of the topic at hand. This is followed by a look at the several elements of TQM, the factors driving these elements and how they inter-play to enhance service delivery and improve competitive advantage. In conclusion, the researcher discusses how total quality management has affected the National Health Service recently and what improvements were reached by it's managers.
