According to kinetic theory :
Correct answer: D. The mean translational K.E. of the molecule is directlyproportional to the absolute temperature
- A. The pressure exerted by a gas is proportional to mean squarevelocity of the molecules
- B. The pressure exerted by the gas is proportional to the rootmean square velocity of the molecules
- C. The root mean square velocity is inversely proportional to thetemperature
- D. The mean translational K.E. of the molecule is directlyproportional to the absolute temperature
Explanation
According to kinetic theory, the mean translational kinetic energy of a gas molecule is directly proportional to theabsolute temperature. This means that as temperature increases, the average kinetic energy of the molecules increases proportionally.

About Kinetic Molecular Theory
Kinetic molecular theory explains gases as rapidly moving particles separated by large distances, with negligible volume and negligible intermolecular attraction in the ideal model. It relates temperature to average kinetic energy and explains gas pressure, Boyle's and Charles's laws, diffusion, effusion and the conditions under which real gases deviate from ideal behavior.
