(N/A) This statement is correct only for an ideal gas. It is impossible to liquefy an ideal gas because there are no intermolecular forces of attraction between the molecules of an ideal gas. Liquefaction requires the presence of intermolecular forces to bring molecules closer together to form a liquid phase.
