Three 5 L flasks, fixed with pressure gauges and small valves, each contain 4 g of gas at 273 K. Flask A contains H2, flask B contains He, and flask C contains CH4. Rank the flask contents in terms of the following properties. (Use the notation >, <, or =, for example B=C>A.)
(a) pressure
(b) average molecular kinetic energy
(c) diffusion rate after the valve is opened
(d) total kinetic energy of the molecules
(e) density
(f) collision frequency
