Assertion (A) : At critical temperature liquid passes into gaseous sta

1.	Assertion (A) : At critical temperature liquid passes into gaseous state imperceptibly and continuously.Reason (R ) : The density of liquid and gaseous phase is equal to critical temperature.
Answer» Both A and R are TRUE and R is the CORRECT explanation of A Both A and R are true but R is not the correct explanation of A A is true but R is FALSE. A is false but R is true. Solution :Both assertion and reason are true and reason is the correct explanation of assertion. At Tc, density of GASEOUS phase and LIQUID are equal due to which liquid passes into gaseous state imperceptibly and continuously.
