Question

Can u explain me Liquefaction of Gases?

Kirti Gogia · Accepted Answer

We know that out of solid, liquids and gases, gases are the most
compressible due to large intermolecular spaces between the
particles of a gas A gas on being compressed will condense into a
liquid, as the constituent molecules will come close to each
other
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)
âˆ’ the temperature at which a gas can be
liquefied

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

Critical volume
(Vc)
âˆ’ 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
