Chemistry - Real Gas Question with Solution | TestHub

We can condense vapour simply by applying pressure

To liquefy a gas, one must lower the temperature below it's critical temperature ( ${\mathrm{T}}_{\mathrm{C}}$ ) and also apply pressure

At critical temperature ( ${\mathrm{T}}_{\mathrm{C}}$ ), there is no distinction between liquid and vapour state. Hence, density of the liquid is nearly equal to density of the vapour

Whatever the pressure applied, a gas cannot be liquified below it's critical temperature ( ${\mathrm{T}}_{\mathrm{C}}$ )
