NEET Physics Kinetic Interpretation of Temperature MCQ Question

Type: MCQ-conceptual-Hard-Class 11

Which of the following statements about the kinetic interpretation of temperature is correct?

A

The average kinetic energy of gas molecules is directly proportional to the absolute temperature.

B

Heavier molecules always possess higher rms speed than lighter molecules at the same temperature.

C

Temperature in a gas is independent of the molecular mass of its constituents.

D

The root mean square speed of gas molecules decreases with increasing temperature.

Correct Answer

Option A

Detailed Explanation

According to the kinetic theory, the average kinetic energy of molecules is directly proportional to the absolute temperature, as indicated by the equation E = (3/2) k_B T. This confirms that statement A is correct.
