A gas has volume `V` and pressure `p`. The total translational kinetic energy of all the molecules of the gas is

3/2 pV only if th gas in monoatomic

3/2 pV only if the gas is diatomic

3/2 pV in all cases

None of above

Text Solution

Verified by Experts

The correct Answer is:

Translational degree of freedom for any type of gas is three. `therefore` Total translational kinetic energy `=3(1/2nRT)=3/2pV`
