At what temperature is the rms velocity ...

At what temperature is the rms velocity of a hydrogen molecule equal to that of an oxygen molecule at `47^@C`?

A

`20 K`

B

`50 K`

C

`40 K`

D

`30 K`

Text Solution

Verified by Experts

The correct Answer is:
A
`C_(H_(2)) = sqrt((3RT)/(M_(H_(2)))) = C_(O_(2)) = sqrt((3R(320 ))/M_(O_(2))) rArr T = 2/ 32 xx 320 = 20 K`
