Question

Describe the role of pressure and temperature in the liquefication of a gas.

Answer 1

Hi there

Two important properties of gases are important in developing methods for their liquefaction: critical temperature and critical pressure. The critical temperature of a gas is the temperature at or above which no amount of pressure, however great, will cause the gas to liquefy.


Thank You

Answer 2

Explanation:

Liquefaction of gases is physical conversion of a gas into a liquid state (condensation). The liquefaction of gases is a complicated process that uses various compressions and expansions to achieve high pressures and very low temperatures. For ex oxygen.
