liquefaction is based on the principle that a low melting metal like tin is made to flow on a sloping surface. in this way it is separated from higher melting impurities

thanx but its not what i needed
liquefaction of gas is the process by which the substances in their gaseous state are converted to liquid state. when pressure on the gas increased,its molecules closer together ,and its temperature is reduced which removes enough energy to make it change from gaseous state to liquid state
thanx this is what i was asking for
