The play An Inspector Calls Persuasive Essay Example For Students
The play An Inspector Calls Persuasive Essay How does Priestley make a drama out of the theme of social responsibility in the play An Inspector Calls?à The play tells the story of a middle class family and how they have all contributed to a young working class womans suicide. Priestley has set the play in 1912 as a way of making the audience of 1946 look back on their past. The consequence of setting the play 30 years or so earlier is that the audience can know more about events than the characters. He is also making people realise how social values have changed, for the better. In a way, the audience can relate to the Birling family, which brings across the message of the play far more intimately. The audience feel like they could be in the same position as the Birlings, bringing the theme of the play closer to home. We will write a custom essay on The play An Inspector Calls Persuasive specifically for you for only $16.38 $13.9/page Order now The dramatic irony relating to the audiences knowledge is particularly apparent in Mr Birlings speech to Gerald and Eric. Priestley is revealing aspects of the character to the audience; in this progress speech there are numerous examples of this device. He paints a very rosy picture of life for them, going on at length about how safe and prosperous the world is. Mr Birling says there isnt a chance of war, the worlds developing so fast itll make war impossible. The audience will immediately pick up on this irony, as the audience will know, the First World War began in 1914 and didnt end until 1918. Millions died. Birling denies there will be any trouble with industrial workers, Dont worry. Weve passed the worst of it. He even pronounces the Titanic unsinkable, Titanicunsinkable, absolutely unsinkable. The Titanic sank on her maiden voyage; she hit an iceberg on the 15th of April 1912, killing 1513 people. In 1921 there was a General Strike affecting most industries. This is dramatic irony. Priestley uses it to make the audience realise what a shock all of these events must have been to the nation. The country had its moral and social values set, a war can change values dramatically, bring the classes closer together. Such naà ¯Ã ¿Ã ½ve remarks make Mr Birling look like a pompous, unreliable fool. He puts such emphasis on class divisions, with statements such as youd think everybody has to look after everybody else, community and all that nonsense. His feelings are a man has to mind his own business and look after himself and his own He is always eager to lecture the younger generation about his views and give them advice. This advice always revolves around his belief that it is each for their own. The theme of the whole play is social responsibility, equality, morals and sharing wealth. Inspector Goole takes the opposing view to Mr Birling, We dont live alone. We are members of one body. We are responsible for each other. He is trying to teach the Birlings that they, as the higher class should have a sense of responsibility for the lower, poorer classes. After the war people had begun to realise the importance of everyone looking after each other. Many men died in the war, the sorrow and rationing of food can only have bought the classes on to a similar level; each family had the same amount of rations, so no longer did the upper classes have money as a way of being better than the lower classes. The whole play could be very dull. There is no change of scene and only six main characters and a maid. The entire play is performed in the dining room of the Birling family. There are no flashbacks, special effects and very few lighting techniques as we, the modern generation would expect. Unlike most plays there is only one plot line and no subplot. However, this brings a naturalistic feel to the play. The audience are present throughout the interrogations. The scandal of the play provides the interest. Priestley knows people love scandal and the way to keep their attention is to make the results of the investigation as scandalous as possible. .u79c458be3a7f86e280c22d808227edbe , .u79c458be3a7f86e280c22d808227edbe .postImageUrl , .u79c458be3a7f86e280c22d808227edbe .centered-text-area { min-height: 80px; position: relative; } .u79c458be3a7f86e280c22d808227edbe , .u79c458be3a7f86e280c22d808227edbe:hover , .u79c458be3a7f86e280c22d808227edbe:visited , .u79c458be3a7f86e280c22d808227edbe:active { border:0!important; } .u79c458be3a7f86e280c22d808227edbe .clearfix:after { content: ""; display: table; clear: both; } .u79c458be3a7f86e280c22d808227edbe { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u79c458be3a7f86e280c22d808227edbe:active , .u79c458be3a7f86e280c22d808227edbe:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u79c458be3a7f86e280c22d808227edbe .centered-text-area { width: 100%; position: relative ; } .u79c458be3a7f86e280c22d808227edbe .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u79c458be3a7f86e280c22d808227edbe .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u79c458be3a7f86e280c22d808227edbe .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u79c458be3a7f86e280c22d808227edbe:hover .ctaButton { background-color: #34495E!important; } .u79c458be3a7f86e280c22d808227edbe .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u79c458be3a7f86e280c22d808227edbe .u79c458be3a7f86e280c22d808227edbe-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u79c458be3a7f86e280c22d808227edbe:after { content: ""; display: block; clear: both; } READ: Ralph (609 words) EssayThe inspector enters at an ironic point in the play, just as Mr Birling is making his speech to Gerald and Eric, wrongly advising them on morals, ethics and social values. At the entrance of the Inspector, Mr Birling asks for more light. This gives the scene a new stark, harsh feel, anticipating a change in atmosphere, setting the scene on edge. Mr Birling presumes, because of his position that he is required to sign a warrant of some sort. In fact, he himself is under investigation. The name Goole may be intentional or coincidental, to give the audience a clue that he may be a ghost, Goole sounds strangely like ghoul, and this may be of some significance. Priestley could be implying that the Inspector could be a ghost, brought to teach the family a lesson. It may not be a coincidence that the Inspector arrived when he did, if he is some sort of ghost or messenger sent to teach the Birlings values he may have entered at that point because of what Mr Birling had just said. The Inspector really brings the play together; he reveals the characters secrets, their thoughtlessness and lack of consideration for others, especially those of a lower class. He will only interrogate one character at a time, more or less in the order of events in the life of Eva. Sheila realises nothing can be hidden from the Inspector early on and decides everyone may as well confess. The Inspector, calmly begins to expose the Birlings flaws, he shows them for what they really are, with no regard for their position in society. The Inspector can always find fault with the Birlings. He twists their words, makes them realise what theyve done. For example, at Mr Birlings remark about how the Inspector has made a mess of their nice little family celebration, the Inspector retorts that when he saw what was left of Eva Smith he thought a nice little promising life there and a nasty mess somebodys made of it. He has thrown Mr Birlings anger back in his face, making him realise how petty he seems. Furthermore, the Inspector can always outwit the Birlings, especially Mr Birling. The Inspector will always take the opposing view to Mr Birling and get the last word, pointing out to Mr Birling that its better to ask for the world than to take it. Eva is cleverly and symbolically named. Priestley has set her up as the archetypal lower class woman. The name Eva is a form of Eve, i.e. Adam and Eve, representing the first and only woman, so she represents the entire female sex. Smith is a common name; therefore she belongs to the lower classes. Eva is the key of the play, the topic of conversation and the reason for the investigation. Most importantly, she is used to evoke emotion from the audience and characters. She binds everything and everyone together.

Argon Facts (Atomic Number 18 or Ar)
Argon Facts (Atomic Number 18 or Ar) Argon is a noble gas with element symbol Ar and atomic number 18. It is best known for its use as an inert gas and for making plasma globes. Fast Facts: Argon Element Name: ArgonElement Symbol: ArAtomic Number: 18Atomic Weight: 39.948Appearance: Colorless inert gasGroup: Group 18 (Noble Gas)Period: Period 3Discovery: Lord Rayleigh and William Ramsay (1894) Discovery Argon was discovered by Sir William Ramsay and Lord Rayleigh in 1894 (Scotland). Prior to the discovery, Henry Cavendish (1785) suspected some unreactive gas occurred in air. Ramsay and Rayleigh isolated argon by removing the nitrogen, oxygen, water, and carbon dioxide. They found the remaining gas was 0.5% lighter than nitrogen. The emission spectrum of the gas did not match that of any known element. Electron Configuration [Ne] 3s2 3p6 Word Origin The word argon comes from the Greek word argos, which means inactive or lazy. This refers to the extremely low chemical reactivity of argon. Isotopes There are 22 known isotopes of argon ranging from Ar-31 to Ar-51 and Ar-53. Natural argon is a mixture of three stable isotopes: Ar-36 (0.34%), Ar-38 (0.06%), Ar-40 (99.6%). Ar-39 (half-life 269 yrs) is to determine the age of ice cores, ground water and igneous rocks. Appearance Under ordinary conditions, argon is a colorless, odorless, and flavorless gas. The liquid and solid forms are transparent, resembling water or nitrogen. In an electric field, ionized argon produces a characteristic lilac to violet glow. Properties Argon has a freezing point of -189.2à °C, boiling point of -185.7à °C, and density of 1.7837 g/l. Argon is considered to be a noble or inert gas and does not form true chemical compounds, although it does form a hydrate with a dissociation pressure of 105 atm at 0à °C. Ion molecules of argon have been observed, including (ArKr), (ArXe), and (NeAr). Argon forms a clathrate with b hydroquinone, which is stable yet without true chemical bonds. Argon is two and a half times more soluble in water than nitrogen, with approximately the same solubility as oxygen. Argons emission spectrum includes a characteristic set of red lines. Uses Argon is used in electric lights and in fluorescent tubes, photo tubes, glow tubes, and in lasers. Argon is used as an inert gas for welding and cutting, blanketing reactive elements, and as a protective (nonreactive) atmosphere for growing crystals of silicon and germanium. Sources Argon gas is prepared by fractionating liquid air. The Earths atmosphere contains 0.94% argon. Mars atmosphere contains 1.6% Argon-40 and 5 ppm Argon-36. Toxicity Because it is inert, argon is considered to be non-toxic. It is a normal component of air that we breathe every day. Argon is used in blue argon laser to repair eye defects and kill tumors. Argon gas may replace nitrogen in underwater breathing mixtures (Argox) to help reduce the incidence of decompression sickness. Although argon is non-toxic, it is considerably more dense than air. In an enclosed space, it may present an asphyxiation risk, particularly near ground level. Element Classification Inert Gas Density (g/cc) 1.40 ( -186 à °C) Melting Point (K) 83.8 Boiling Point (K) 87.3 Appearance Colorless, tasteless, odorless noble gas Atomic Radius (pm):à 2- Atomic Volume (cc/mol): 24.2 Covalent Radius (pm): 98 Specific Heat (20à °C J/g mol): 0.138 Evaporation Heat (kJ/mol): 6.52 Debye Temperature (K): 85.00 Pauling Negativity Number: 0.0 First Ionizing Energy (kJ/mol): 1519.6 Lattice Structure: Face-Centered Cubic Lattice Constant (Ãâ¦): 5.260 CAS Registry Number: 7440ââ¬â37ââ¬â1 Argon Trivia The first noble gas to be discovered was argon.Argon glows violet in a gas discharge tube. It is the gas found in plasma balls.William Ramsay, in addition to argon, discovered all the noble gases except radon. This earned him the 1904 Noble Prize in Chemistry.The original atomic symbol for argon was A. In 1957, the IUPAC changed the symbol to the current Ar.Argon is the 3rd most common gas in Earths atmosphere.Argon is produced commercially by fractional distillation of air.Substances are stored in argon gas to prevent interactions with the atmosphere.
