NEET Physics Kinetic Interpretation of Temperature MCQ Question
Which of the following statements about the kinetic interpretation of temperature is correct?
The average kinetic energy of gas molecules is directly proportional to the absolute temperature.
Heavier molecules always possess higher rms speed than lighter molecules at the same temperature.
Temperature in a gas is independent of the molecular mass of its constituents.
The root mean square speed of gas molecules decreases with increasing temperature.
Correct Answer
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.
