The rms speed of the molecules of a gas ...

The rms speed of the molecules of a gas in a vessel is `400ms^(-1)`. If half of the gas leaks out at constant temperature, the rms speed of the ramaining molecules will be…………..

A

`200sqrt2m//s`

B

`200m//s`

C

`400m//s`

D

`400sqrt2m//s`

Text Solution

Verified by Experts

The correct Answer is:
C

`C=sqrt((3RT)/(M))`
It depends only upon the temperature. It is independent of pressure. As there is no change of temperature, C will not change.
