NEET Physics Kinetic Interpretation of Temperature MCQ Question
At a given temperature, which type of molecules will have the greater root mean square speed?
Lighter molecules
Heavier molecules
Molecules of varying mass
All molecules have the same speed
Correct Answer
Detailed Explanation
At the same temperature, lighter molecules have greater rms speed according to the kinetic theory of gases. This is derived from the relationship between molecular mass and speed as described in the text.
