Two flasks `A` and `B` have equal volume. `A` is maintained at `300 K` and `B` at `600 K`. While `A` contains `H_(2)` gas, `B` has an equal mass of `CH_(4)` gas. Assuming ideal behaviour for both the gases, which of the following statement is true about the velocities of molecules?A. The molecules in flasks `A` and `B` are moving with the same veocity.B. The molecules in flask `A` are moving two times faster than the molecules in flask `B`.C. The molecules in flask `B` are moving two times faster than the molexules in flask `A`.D. The molecules in flask `A` are moving four times faster than the molecules in flask `B`. |

Answer» `KE` per mole `=(3)/(2)RT` ` :. KE prop T` `(KE_(1))/(KE_(2))=(T_(A))/(T_(B))=(100)/(200)=(1)/(2)` |
