Liquefaction of gases is the process by which a gas is converted to a liquid.
The critical temperature of a gas is the temperature at or above which no amount of pressure will cause the gas to liquefy. The minimum pressure required to liquefy the gas at the critical temperature is called the critical pressure.
Liquefaction of gas occurs when its molecules are pushed closer together. It can be done by one of two methods: by increasing the pressure on the gas or by lowering the temperature of the gas.
Atmospheric gases can be liquefied by applying pressure and lowering the temperature. When enough pressure is applied, the gases are highly compressed into a small volume. The particles of gases get so close together that they start attracting one another sufficiently to form a liquid. When a gas is compressed too much by applying high pressure, a lot of heat is produced. So, while applying pressure to liquefy gases, it is necessary to lower their temperature (or cool them) to take away the heat produced during compression.
