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 liquify even on applying high pressure until it is cooled. Explain this phenomenon.

This is a short answer type question as classified in NCERT Exemplar
On increasing the pressure slightly the gas 'A' liquefies but gas B does not liquify even on applying high pressure until it is cooled at same conditions of temperature and pressure filled in equal capacity containers it happens because the gas ‘A’ being at the critical temperature liquifies on slightly increasing the pressure and gas ’B’ being at higher temperature than critical temperature does not liquifies even on applying high pressure until it is cooled.
