Question

Three 4−L flasks, fixed with pressure gauges and small valves, each contain 9 g of gas at 281 K. Flask A contains He, flask B contains H₂, and flask C contains CH₄. Rank the flask contents in terms of:

Multiple Choice:

(a) pressure.

	A > B > C
	A > C > B
	B > C > A
	B > A > C
	C > B > A
	C > A > B
	A = B = C

(b) average molecular kinetic energy.

	A > B > C
	A > C > B
	B > C > A
	B > A > C
	C > B > A
	C > A > B
	A = B = C

	A > B > C
	A > C > B
	B > C > A
	B > A > C
	C > B > A
	C > A > B
	A = B = C

(d) total kinetic energy of the molecules.

	A > B > C
	A > C > B
	B > C > A
	B > A > C
	C > B > A
	C > A > B
	A = B = C

(e) density.

	A > B > C
	A > C > B
	B > C > A
	B > A > C
	C > B > A
	C > A > B
	A = B = C

(f) collision frequency.

	A > B > C
	A > C > B
	B > C > A
	B > A > C
	C > B > A
	C > A > B
	A = B = C
