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 is
Answer» According to kinetic theory of gases, `v_(rms)=sqrt((3RT)/(M)), ((v_(rms))_(H))/((v_(rm s))_(He))=sqrt((M_(He))/(M_(H)))` i.e. `v_(H)=sqrt((4//2))v_(He=sqrt(2)(V_He))`
