Question

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

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is not the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is A Both A and R are true and R is the correct explanation of A

Both A and R are correct and the reason for A is also correct.

At critical temperature density of liquid becomes equal to its vapour phase. Due to which liquid changes into gaseous state imperceptibly and continuously.
