Question

Let $\overrightarrow{v},v_{rms}$ and $v_2$ respectively denote the mean speed, root mean square speed and most probable speed of the molecules in an ideal monoatomic gas at absolute temperature T. The mass of a molecule is m. Then

• A.
• B.
• C.
• D.

Answer 1

Answer: (C), (D)

The correct options are
C

D

the average velocity of gas molecules is $v=\sqrt{\frac{8RT}{\pi M}}$

Most probable velocity is $=\sqrt{\frac{2RT}{M}}$

Root mean square velocity =$\sqrt{\frac{3RT}{M}}$
