The critical temperature of the gas is the temperature

Question

The critical temperature of the gas is the temperature (A) at which Charle's law is obeyed (B) at which Boyle's law is obeyed (C) above which the gas cannot be liquefied (D) at which all molecular motion ceases

Tardigrade Admin · Accepted Answer

By definition, critical temperature is the temperature, above which the gas cannot be liquified however large pressure be applied on it. The gas molecules get sufficient kinetic energy above this temperature and no amount of force can bring them together and liquify the gas.
