Q. 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
Explanation
(d) Since $v_{rms} \propto \sqrt{T}.$ Also mean square velocity $\overline{v^{2}} = v_{rms}^{2}$
