1.	A vessel constant oxygen at 400K . Another similar vessel constains an equal mass of hydrogen at 300K. The ration of the rms speed of molecules of hydrogen and oxygen is
Answer» `4/3` `3/4` `3sqrt2` `2sqrt3` SOLUTION :`nu_(RMS)=sqrt((3RT)/M),(nu_(rms))_(H_(2))/(nu_(rms))_(O_(2))=sqrt(300/2xx32/400)=2sqrt3`
