Answer to Question #182682 in Physical Chemistry for Khushi

Question

What is the principle of liquefaction of gases? Describe any one method used for the liquefaction of

gases.

Answer 1

Liquefaction of gases is the process by which substances in their gaseous state are converted to the liquid state. When pressure on a gas is increased, its molecules closer together, and its temperature is reduced, which removes enough energy to make it change from the gaseous to the liquid state.

In general, gases can be liquefied by compressing the gas at temperatures less than its critical temperature.
