Question

Five molecules of an ideal gas have velocities 2, 3, 4, 4 and 5 m/s. If their average velocity is $\bar v$ and their RMS velocity is $V_{rms}$ then

A

$v_{rms}^2>\bar v^2$

B

$v_{rms}=\bar v$

C

$v_{rms}<\bar v$

D

$v_{rms}\bar v$ =1

Answer

$v_{rms}^2>\bar v^2$

Explanation

Solution

The correct option is (A): $v_{rms}^2>\bar v^2$
