Relation between pressure (P) and average kinetic energy per unit volume of gas (E ) is

A

`P=1/2E`

B

`P=E`

C

`P=3/2E`

D

`P=2/3E`

Text Solution

Verified by Experts

The correct Answer is:
D
As `P = 1/3 rho v_(rms)^2`
and `KE = E = 1/2 rho v_(rms)^2` (energy per unit volume)
`:. P = 2/3 E`.
