QuestionThree 5-L flasks, fixed with pressure gauges and small valves, each contain 1 g of gas at 294 K . Flask A contains $\mathrm{CH}_{4}$, flask B contains He , and flask C contains $\mathrm{H}_{2}$. Rank the flask contents in terms of the following:
Part 1 of 6 pressure: $C>B>A$ $\square$ - $\square$
Part 2 of 6 average molecular kinetic energy: $\square$ $A=B=C$ 7 $\square$
Part 3 of 6 diffusion rate after valve is opened: $\square$ (Choose one) $\mathbf{V}$
Part 4 of 6 total kinetic energy of the molecules: (Choose one) $\mathbf{V}$ $\square$
Part 5 of 6 density: (Choose one) $\mathbf{V}$ $\square$
Part 6 of 6 collision frequency: (Choose one) $\boldsymbol{V}$ $\square$
