NEET Physics Kinetic Interpretation of Temperature MCQ Question
Type: MCQ-numerical-Easy-Class 11
Given that the root mean square speed (v_rms) of nitrogen gas molecules at 300 K is 516 m/s, what would be the approximate v_rms for a gas with half the molecular mass of nitrogen at the same temperature?
A
730 m/s
B
516 m/s
C
364 m/s
D
1032 m/s
Correct Answer
Option A
Detailed Explanation
For a gas with half the molecular mass, v_rms is greater by a factor of sqrt(2), resulting in 516 * sqrt(2) ≈ 730 m/s.
