The root mean square velocity of hydroge...

The root mean square velocity of hydrogen molecule at `27^(@)C is (upsilon_(H)` and that of oxygen at `402^(@)C is (upsilon_(0)`, then

Text Solution

Verified by Experts

The correct Answer is:
C
`(upsilon_H)/(upsilon_O) = sqrt((T_H)/(T_O)) = sqrt((27+273)/(402+273)) = sqrt(300)/(675)) = sqrt(4/9) = 2/3`
or `2upsilon_(O) = 3upsilon_(H)`.
