Two bulbs A and B of equal capacity are ...

Two bulbs `A` and `B` of equal capacity are filled with `He` and `SO_(2)`, respectively, at the same temperature.
(a) If the pressures in the two bulbs are same, what will be the ratio of the velocities of the molecules of the two gases?

A

`3:4`

B

`81:256`

C

`4:3`

D

`256:81`

Text Solution

Verified by Experts

The correct Answer is:
C
According to Wien's displacement law,
`lambdaT`= constant
`thereforeT_(1)/T_(2)=lambda_(2)/lambda_(1) = 480/360 = 4/3`
