Two flasks `A` and `B` of equal volume containing equal masses of `H_(2)` and `CH_(4)` gases are at `100 K` and `200 K` temperature, respectively. Which of the following is true about the total `KE` (Kinetic energy)?A. Total `KE` of `H_(2)` is four times that of `CH_(4)`.B. Total `KE` of `CH_(4)` is four times that of `H_(2)`.C. Total `KE` of `H_(2)` is two times that of `CH_(4)`.D. Total `KE` of `CH_(4)` is two times that of `H_(2)`. |

Answer» Total `KE=Koverline(E)(per mole)xxNumber of molecules` Total `KE_(A)=(3)/(2)KT_(A)N_(A)` `n_(A)=(m)/(2)`, `n_(B)=(m)/(16) :. (n_(A))/(n_(B))=8` `:. (Total KE_(A))/(Total KE_(B))=(T_(A)N_(A))/(T_(B)N_(B))=(1)/(2)xx8=4` |
