Question

The rms speed of the molecules of different ideal gases, maintained at the same temperature are the same.

• A. True
• B. False

Answer 1

The correct option is B False

Two different gases at same temp.

have different $V_{rms}$

$V_{rms}=\sqrt{\frac{3RT}{M}}$

$V_{rms}\propto \frac{1}{\sqrt{M}}$

since different gases have different $M$ ( molar mass) $V_{rms}$ is different.
