The root mean square velocity of an ideal gas at constant pressure varies with density d as

A

`d^(2)`

B

`d`

C

`sqrtd`

D

`1//sqrtd`

Text Solution

Verified by Experts

The correct Answer is:
D
By definition r.m.s. velocity is
`u = sqrt((3PV)/(m xx N_(0))) = sqrt((3P)/(N_(0)).(1)/(d))`
or `u prop (1)/(sqrtd)` ( `:.` all other terms are constant)
