NEET Physics Kinetic Interpretation of Temperature MCQ Question
At a given temperature, which statement is true regarding the root mean square speed of gaseous molecules?
Lighter molecules have a greater root mean square speed than heavier molecules.
All molecules have the same root mean square speed regardless of their mass.
Heavier molecules move faster than lighter molecules at the same temperature.
The root mean square speed is independent of temperature.
Correct Answer
Detailed Explanation
According to the NCERT context, it follows from the kinetic theory that at the same temperature, lighter molecules have a greater root mean square speed.
