Two vessel having equal volume contain molecular hydrogen at one atmosphere and helium at two atmospheres respectively. What is the ratio of rms speed of hydrogen molecule to that of helium molecule? ( Assume both the samples are at same temperature)

Text Solution

Verified by Experts

According to kinetic theory of gases .
`v_(rms)=sqrt((3RT)/(M)),(v_(H))/(v_(He))=sqrt((M_(He))/(M_(H)))`
i.e., `V_(H)=sqrt((4//2)V_(He))=sqrt(2)(v_(He))`
