The rms speed of oxygen at room temperat...

The rms speed of oxygen at room temperature is about `500m//s`. The rms speed of Hydrogen at the same temperature is about

Text Solution

Verified by Experts

RMS speed is given by `V_(rms)=sqrt((3RT)/M_w)`
At constant temperature `V_(rms)prop1/sqrt(M_w)`
Ratio of `V_(rms)` of oxygen and hydrogen `((V_(rms))_O)/((V_(rms))_H)=sqrt(M_(wH)/(H_(wO))`
`implies(500)/((V_(rms))H)=sqrt(2/(32))=1/4implies(V_(rms))_H=2000 m//s`
