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

A

`(3)/(2) PV` only if the gas is monoatomic.

B

`(3)/(2) PV` only if the gas is diatomic.

C

`gt(3)/(2) PV` if the gas is diatomic.

D

`(3)/(2) PV` in all cases.

Text Solution

Verified by Experts

The correct Answer is:
D
Total translational `KE`
