The ratio among most probable velocity, mean velocity and root mean velocity is given by

A

`1:2:3`

B

`1: sqrt2 : sqrt3`

C

`sqrt2 : sqrt3 : sqrt8//pi`

D

`sqrt2 : sqrt8//pi : sqrt3`

Text Solution

Verified by Experts

The correct Answer is:
D
Most probable velocity : mean velocity :`mu_(rms)`
` = sqrt((2RT)/(M)) : sqrt((8RT)/(piM) : sqrt((3RT)/(M))`
`= sqrt2 : sqrt(8/pi) : sqrt3`
