Question

The root mean square speed of one mole of a monoatomic gas having molecular mass `M` is `u_(rms)` The relation between the average kinetic energy `(E)` of the gas and `u_9rms)` is .
A. `u_(rms)=sqrt((3E)/(2M))`
B. `u_(rms)=sqrt((2E)/(3M))`
C. `u_(rms)=sqrt((2E)/(M))`
D. `u_(rms)=sqrt((E)/(3M))`

Answer 1

`u_(rms)= sqrt((3RT)/(M))`
and `K.E. =(3)/(2)RT :. u_(rms) = sqrt((2E)/(M)` .
