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 behaviours for both the gases, answer the following:
Flask in which molecules are moving faster

Options

A. `A`
B. `B`
C. Both `A` and `B`
D. None

Explanation

To determine which flask has molecules that are moving faster, we can use the formula for the average speed of gas molecules, which is derived from the kinetic theory of gases. The average speed \( v \) of a gas can be expressed as:

\[ v = \sqrt{\frac{8RT}{\pi m}} \]

where:
- \( R \) is the universal gas constant,
