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’ liquefies but gas B does not liquefy even on applying high pressure until it is cooled. Explain this phenomenon.

Answers (1)

This is based on the phenomenon of critical temperature; here, Gas 'A' liquefies easily, hence, it is below the critical temperature, whereas Gas' B' doesn't liquefy even on applying high pressure; hence it is above the critical temperature.
