The absolute temperature of a gas is determined by

A

The average momentum of the molecules

B

The velocity of sound in the gas

C

The number of molecules in the gas

D

The mean square velocity of the molecules

Verified by Experts

The correct Answer is:

D

Since `v_(rms) prop sqrt(T)` . Also mean square velocity `bar(v^2)=v_(rms)^2`
