Assertion :Gases do not liquefy above their critical temperature, whatever the high pressure is applied. Reason :Above critical temperature, molecular speed is high and intermolecular force cannot hold the molecules together.

Assertion: Gases do not liquefy above their critical temperature, whatever the high pressure is applied. Reason:Above critical temperature, molecular speed is high and intermolecular force cannot hold the molecules together Explanation: Assertion is the true statement as, according to the Andrews only, the definition of critical temperature says that it is the temperature above which gas can never be liquefied even if pressure is applied. It is because of the reason that the molecular speed is very high that intermolecular forces cannot hold the molecules together. They escape because of their
