Question

Quizplus · Accepted Answer

The critical temperature is the highest temperature at which a gas can be liquefied. Above the critical temperature, it is not possible to liquefy a gas regardless of the amount of pressure applied to it. Therefore, the maximum temperature at which a gas can be liquefied is just below the critical temperature.
