All vapour at a temperature higher than the critical temperature Tc is considered as gases (highly super-heated vapour).

  • When a vapour condenses from a temperature below than the critical temperature Tc it changes it states from vapour to liquid.
  • When gases (highly super-heated vapour) condenses, it falls into the super-critical state which is not easily liquifiable.
  • A gas (highly superheated vapour) is thus approximated as an ideal gas as it never comes under liquid phase.
