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

Temperature is directly proportional to the average kinetic energy of the gas molecules.

B

Temperature remains unchanged regardless of the molecular mass of the gas.

C

The average speed of gas molecules increases as temperature decreases.

D

The root mean square speed of gas molecules is independent of temperature.

Correct Answer

Option A

Detailed Explanation

Temperature is directly proportional to the average kinetic energy of gas molecules, as indicated by the relationship = (3k_B T/m). Option B is incorrect because temperature affects the speeds of molecules, while option C is false as higher temperatures lead to increased speeds. Option D is incorrect since the root mean square speed depends on temperature.
