Q. Applying pressure and reducing temperature can liquefy gases.

Q. Two different gases 'A' and 'B' are filled in separate containers of equal capacity under the same conditions of temperature and pressure. On increasing the pressure slightly, the gas 'A' liquifies but gas 'B' does not liquefy even on applying high pressure until it is cooled.

Explain this phenomenon.

Q. Assertion (A): Gases do not liquefy above their critical temperature, even on applying high pressure.
Reason (R): Above critical temperature, the molecular speed is high and intermolecular attractions cannot hold the molecules together because they escape because of high speed.
