If the `rms` speed of gas molecules is `x cm s^(-1)` at a pressure of `p` atmospheres, then the `rms` speed at a pressure of `2p` atmospheres and constant temperature will be

A

x

B

2x

C

4x

D

`(x)/(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
`u=sqrt((3RT)/(M))=sqrt((3PV)/(M))`
As temperature is constant PV is constant
Hemce r.m.s is constant even if pressure is doubled.
