Two vessels have equal volums. One of them contains hydrogen at one atmosphere and the other helium at two atmosphere. If both the samples are at the same temperature, the `rms` velocity of the hydrogen molecules is

A

equal to that of helium

B

twice that of helium

C

half that of helium

D

`sqrt(2)` times that of helium

Text Solution

Verified by Experts

The correct Answer is:
D
`(V_(1))/(V_(2))=sqrt((M_(2))/(M_(1)))=sqrt((4)/(2))=sqrt(2)V_(1)=sqrt(2)V_(2)`
