The liquefaction of a gas takes place when the intermolecular forces of attraction become so high that they bind the gas molecules together to form the liquid state.
The intermolecular forces of attraction can be
increased either by increasing the pressure so that the molecules come close together or by cooling the gas so that the kinetic energy of the molecules decreases and they become slower.

EXAMPLE: For example, liquid nitrogen must be brought to a very low temperature (compared to Standard Temperature and Pressure (S.T.P.), but not to absolute zero) and under high pressure to compress the gas.
The gas, once liquidification begins and a liquid begins to form, is brought to a lower pressure. The air, now expanding, cools very quickly.
at high temperatures, despite high pressure, the gases cannot be liquefied. Also with the increase in temperature, the gases show significant deviation from the ideal behavior. In the case of carbon dioxide, at 30.98° C, the gas started changing into a liquid.
