Vedclass · Answer

(D) According to the kinetic theory of gases,the absolute temperature $T$ of an ideal gas is related to the average kinetic energy of its molecules.The average kinetic energy per molecule is given by $\frac{1}{2} m v_{rms}^2 = \frac{3}{2} k_B T$,where $m$ is the mass of a molecule,$v_{rms}$ is the root mean square velocity,and $k_B$ is the Boltzmann constant.From this relation,we can see that $T \propto v_{rms}^2$.Therefore,the absolute temperature is directly proportional to the mean square velocity of the molecules.
