NEET Physics Kinetic Interpretation of Temperature MCQ Question
Which of the following statements about the kinetic interpretation of temperature is correct?
Temperature is proportional to the average kinetic energy of the molecules in a gas.
Temperature is independent of the molecular mass of the gas.
Temperature increases with the decrease of molecular speed.
Kinetic theory suggests that gases have significant inter-atomic forces that affect temperature.
Correct Answer
Detailed Explanation
Statement A is correct as the kinetic theory explains that the temperature of a gas is related to the average kinetic energy of its molecules. Statement B is incorrect because temperature is affected by molecular mass, as lighter molecules generally move faster at a given temperature. Statement C is incorrect because temperature increases with an increase in molecular speed. Statement D is incorrect as kinetic theory assumes negligible inter-atomic forces in gases.
