Solution

The correct options are A In flask A the molecules move faster than B C Flask A contains greater number of molecules than BThe average velocity for the gas molecules is given by =√8RTπM.So, the molecules which have more TM will have greater average velocity and will move faster . For H2 in flask A, TM= 6002 For flask B, TM= 30016 ∴ H2 moves faster. We know, n=mM.For H2. As masses of two gas are same, then we have n∝1M.For H2, there are more number of moles , hence greater number of molecules as compared to the one in flask B ( containingCH4 ).
