Question

For a diatomic molecule, according to kinetic theory of gases

• A. The pressure exerted by the gas is proportional to the mean velocity of the molecule.
• B. The pressure exerted by the gas is proportional to the root mean square velocity of the molecule.
• C. The mean translational kinetic energy of the molecule is proportional to the absolute temperature.
• D. The root mean square velocity of the molecule is inversely proportional to temperature.

Answer 1

The correct option is C

The mean translational kinetic energy of the molecule is proportional to the absolute temperature.

According to the kinetic theory of gases the mean translational kinetic energy of the molecule is proportional to the absolute temperature.
