Quizplus · Accepted Answer

The critical temperature is the temperature above which a gas cannot be liquefied, regardless of the pressure applied. It is the maximum temperature at which the liquid state can exist. Above this temperature, the gas is said to be in a supercritical state, which cannot be classified as a liquid or a gas.
