NEET Physics Kinetic Interpretation of Temperature MCQ Question
Which of the following statements about the kinetic interpretation of temperature is correct?
At a given temperature, the average kinetic energy of gas molecules is the same for all gases.
Lighter gas molecules always move slower than heavier molecules at the same temperature.
The root mean square speed of gas molecules is independent of their mass.
The average kinetic energy of gas molecules increases with temperature.
Correct Answer
Detailed Explanation
According to the kinetic interpretation of temperature, the average kinetic energy of gas molecules is directly proportional to the absolute temperature, thus increasing with temperature. This is supported by the equation relating average kinetic energy to temperature.
