Explanation:

Liquefaction of gases is the process by which a gas is converted to a liquid. Liquefaction of a gas occurs when its molecules are pushed closer together. Gas molecules can be squeezed together by one of two methods: by increasing the pressure on the gas or by lowering the temperature of the gas.

Answer 2

Answer:

In general, gases can be liquefied by one of three methods:

(1) by compressing the gas at temperatures less than its critical temperature

(2) by making the gas do some kind of work against an external force, which causes the gas to lose energy and change to the liquid state;

(3) by making gas do work against its .
