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 temperature of the gas.
At higher temperatures, heavier gas molecules always have greater average speeds than lighter molecules.
Temperature is a measure of the total energy of the gas molecules.
The mean square speed of gas molecules decreases as the temperature increases.
Correct Answer
Detailed Explanation
The average kinetic energy of gas molecules is given by the formula (3/2) k_B T, indicating that it is directly proportional to the temperature of the gas. This aligns with the kinetic interpretation of temperature.
