The temperature at which the rms velocity of oxygen molecules equals to that of nitrogen molecules at `0^(@)C` is

A

`312^(@)C`

B

`292^(@)C`

C

`195^(@)C`

D

`39^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
D
`V_("rms")=sqrt((3RT)/(M))`
`therefore(3Rtheta)/32=(3Rxx273)/28" "thereforetheta=312K=39^(@)C`
