Vedclass · Answer

(D) An ideal gas is defined as a gas where there are no intermolecular forces of attraction between the molecules.Liquefaction of a gas occurs when intermolecular forces become strong enough to hold the molecules together in the liquid state.Since an ideal gas assumes zero intermolecular forces,it is impossible to overcome the kinetic energy of the molecules to bring them into a liquid state,regardless of the pressure or temperature applied.
