NEET Physics Kinetic Interpretation of Temperature MCQ Question with Solution

What is the root mean square speed $v_{rms}$ of a gas molecule at a temperature $T = 300$ K, if the molecular mass $m$ is $28 \times 10^{-3}$ kg/mol?

A

516 m/s

B

258 m/s

C

129 m/s

D

1032 m/s

Correct Answer

Option A

Detailed Explanation

From the context, the root mean square speed $v_{rms} = \sqrt{\frac{3k_BT}{m}}$ is calculated to be 516 m/s for nitrogen gas at 300 K using the given molecular mass.
