Question

Can u explain me  Liquefaction of Gases?​

Answer 1

A gas can therefore be liquefied by increasing its pressure and decreasing its temperature. Following are the conditions that are defined when considering liquefaction of gases

Critical temperature (Tc) − the temperature at which a gas can be liquefied

Critical pressure (pc) − the pressure of a gas at critical temperature

Critical volume (Vc) − the volume of 1 mole of a gas at critical temperature

Isotherm of carbon dioxide is shown in the figure.

Critical temperature, critical pressure and critical volume are called critical constants.

Answer 2

Liquefaction of gases is physical conversion of a gas into a liquid state (condensation).
