JEE Main 2026 (4 Apr, Shift 2) Physics Q33: Kinetic Theory

Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: If the average kinetic energy of $\mathrm{H_2}$ and $\mathrm{O_2}$ molecules, kept in two different sized containers are same, then their temperatures will be same.
Reason R: The r.m.s. speed of $\mathrm{H_2}$ and $\mathrm{O_2}$ molecules are same at same temperature.
Choose the correct answer from the options given below

Accepted Answer

Option 3: $\mathbf{A}$ is true but $\mathbf{R}$ is false
