Question

Define critical volume and critical pressure.​

Answer 1

Answer:

The critical temperature is the temperature at which a gas changes into liquid. ... The volume of one mole of a gas volume liquefied at critical temperature is known as the critical volume (Vc) while the pressure required to liquefy the gas at critical temperature is called as the Critical pressure (pc).

Answer 2

Critical pressure

It is the pressure required to liquify a gas at the critical temperature.

Critical volume

It is the volume of 1 mole of gas at critical temperature and pressure
