Question

define critical temperature critical volume and Critical pressure of gas ?​

Answer 1

Answer:

the temperature the pressure and the volume at which gas tends to liquefy is called critical temperature pressure and volume respectively

Answer 2

Answer:

Critical Pressure ($P_{c}$) :

• At critical temperature, a certain pressure is needed to liquefy the gas. So, this pressure at critical temperature is called the critical pressure.

Critical Volume ($V_{c}$) :  

• The volume occupied by one mole of a gas at its critical temperature and critical pressure is known as the critical volume.
