three 6-L flasks filled with pressure gauges and small valves each
contain 2 g of gas at 268K. Flask A contains H2 flask B contains
CH4 and flask C contains He. Rank the flask contents in terms of :
pressure
average molecular kinetic energy
diffusion rate after valve is opened
total kinetic energy of the molecules
density
collision frequency
(please do in form of A>B>C)

Three 3−L flasks, fixed with pressure gauges and small valves,
each contain 7 g of gas at 271 K. Flask A contains H2, flask B
contains He, and flask C contains CH4. Rank the flask contents in
terms of:
(e) density.
A > B > C
A > C > B
B > C > A
B > A > C
C > B > A
C > A > B
A = B = C
