複選題
4. Consider the following gas samples:
Sample A: \( S_2(g) \), n=1 mol, T=800 K, P=0.20 atm
Sample B: \( O_2(g) \), n=2 mol, T=400 K, P=0.40 atm
(A)The volume of sample A is twice the volume of sample B.
(B)The mean square velocity of molecules in sample A is twice as large as the mean square velocity of molecules in sample B.
(C)The fraction of molecules in sample A, having a kinetic energy greater than some high fixed value, is larger than the fraction of molecules in sample B, having kinetic energies greater than that same high fixed value.
(D)Assuming identical intermolecular forces in the two samples, sample A should be more nearly ideal than sample B.
(E)The average kinetic energy of the molecules in sample A is twice the average kinetic energy of the molecules in sample B.
