Question

Assertion: Critical temperature of CO₂ is 304 K, it cannot be liquified above 304 K.

Reason: At a certain temperature,volume ∝ 1/pressure

(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 correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

Correct option  (b) Both A and R are true but R is not correct explanation of A

Explanation:

Critical temperature of a gas maybe defined as that temperature above which it cannot be liqufied however high pressure may be applied on the gas. Hence, CO₂ cannot be liquified above its critical temperature.

According to Boyle's law
