The ratio between the root mean square velocity of `H_(2)` at 50 K and that of `O_(2)` at 800 K is:

A

`4`

B

`2`

C

`1`

D

`(1)/(4)`

Text Solution

Verified by Experts

`mu_(ms)=sqrt((3RT)/(M)), mu_(ms) prop sqrt((T)/(M))`
`:. (mu_(ms)(H_(2) at 50 K))/(mu_(ms)(O_(2) at 800 K))=sqrt((50)/(2)xx(32)/(800))=1`
So the correct choice is (`c`).
