Start with solid Argon and explain how to make Argon change to the liquid state and then to the gaseous state.
Answers
Explanation:
Argon is an integral part of the air, so that is why it is gotten from air mixture. In industry, air is separated by liquefaction. This is done due to the use of low temperatures, high and low pressure.
Deep cooling of gases make them take liquid form. Since the temperature of liquefaction is different for each gas, it becomes possible to separate liquids in different phases. The combination of high and low pressure allows you to make process of distillation better and faster. As a result, from the air separation unit goes out different gas fractions, containing relatively small amounts of impurities. For argon, these impurities can be mainly nitrogen and oxygen.Gaseous under normal conditions and liquid as a resut of cooling till -185.9 degrees, argon became solid at -189.6 degrees.

Explanation:
- Distillation process can be made better and faster or efficient by combining low and high pressures.
- In solid, liquid or gaseous state, Argon (Ar) is odourless, colourless, nontoxic and non-inflammable.
- Extraction of Argon can be performed industrially from liquid air in cryogenic air and this separation is performed by fractional distillation.
- Nitrogen gas from the atmosphere is heated with the help of hot magnesium or calcium, formation of nitride can be seen as a product to this reaction and Argon is released in small amount as impurity.
