JEE Main 2025 — Kinetic Theory of Gases Question with Solution
JEE Main 2025 (28 Jan Shift 1)
Question
For a particular ideal gas which of the following graphs represents the variation of mean squared velocity of the gas molecules with temperature?
Choose an option
Show full solutionCorrect option: B
Correct answer
B
Step-by-step explanation
$\begin{aligned}
& \mathrm{V}_{\mathrm{ms}}=\sqrt{\frac{3 \mathrm{RT}}{\mathrm{M}}} \\
& \mathrm{~V}_{\mathrm{rms}}^2=3 \mathrm{RT} / \mathrm{M}
\end{aligned}$
Hence we can conclude that is directly proportional to temperature
Graph will be straight line
