Vedclass · Answer

(A) At the critical temperature $(T_c)$,the distinction between the liquid and gaseous phases disappears. This is because the density of the liquid phase becomes equal to the density of the gaseous phase at this temperature. Consequently,the liquid passes into the gaseous state imperceptibly and continuously,meaning there is no phase boundary. Both the Assertion and the Reason are correct,and the Reason correctly explains why the transition occurs in this manner.

Assertion : At critical temperature,liquid passes into gaseous state imperceptibly and continuously.
Reason : The density of liquid and gaseous phase is equal at critical temperature.
