Vedclass · Answer

(A) The critical temperature $(T_c)$ of a gas is the temperature above which it cannot be liquefied,no matter how much pressure is applied. This is because,above $T_c$,the kinetic energy of the gas molecules is so high that the intermolecular forces of attraction are insufficient to hold the molecules together in the liquid state. Therefore,both the Assertion and the Reason are correct,and the Reason is the correct explanation of the Assertion.

Assertion : Gases do not liquefy above their critical temperature,even on applying high pressure.
Reason : Above critical temperature,the molecular speed is high and intermolecular attractions cannot hold the molecules together because they escape because of high speed.
