Given below are two statements; one is labelled as Assertion (A) and the other is labelled as Reason(R). Assertion (A): Gases do not liquify above their critical temperature even on applying high pressure. Reason (R) : Above critical temperature molecular speed become high and inter molecular attractions can not hold molecules together. In the light of the above statements, choose the most appropriate answer from the

Step-by-step solution

- Assertion (A) is true because gases do not liquefy above their critical temperature, no matter how much pressure is applied. This is because above the critical temperature, the kinetic energy (or speed) of the gas molecules is too high for intermolecular forces to bring them close enough to form a liquid. - Reason (R) is also true and correctly explains the assertion, as above the critical temperature, the molecular speed is high, and intermolecular attractions are too weak to hold the molecules together, prevent
