Vedclass · Answer

(D) According to the Kinetic Molecular Theory of Gases,the pressure $P$ is given by the formula $P = \frac{1}{3} \rho u_{rms}^2$,where $\rho$ is the density and $u_{rms}$ is the root mean square velocity. This implies $P \propto u_{rms}^2$ (mean square velocity). Furthermore,the average translational kinetic energy $E_k$ of gas molecules is given by $E_k = \frac{3}{2} k_B T$,where $k_B$ is the Boltzmann constant and $T$ is the absolute temperature. Thus,$E_k \propto T$. Therefore,the statement that the average translational kinetic energy is directly proportional to the absolute temperature is correct.
