1.	Two vessels have equal volums. One of them contains hydrogen at one atmosphere and the other helium at two atmosphere. If both the samples are at the same temperature, the `rms` velocity of the hydrogen molecules isA. equal to that of heliumB. twice that of heliumC. half that of heliumD. `sqrt(2)` times that of helium
Answer» Correct Answer - D `(V_(1))/(V_(2))=sqrt((M_(2))/(M_(1)))=sqrt((4)/(2))=sqrt(2)V_(1)=sqrt(2)V_(2)`
