25. Consider the following gas samples:

Which of the following statements is NOT TRUE?

(A) Assuming identical intermolecular forces in the two samples, sample M should be more
nearly ideal than sample N.

(B) The root-mean-square velocity of molecules in sample M is twice as large as the root-
mean-square velocity of molecules in sample N.

(C) The average kinetic energy of the molecules in sample M is twice the average kinetic
energy of the molecules in sample N.

(D) The fraction of molecules in sample M having kinetic energies greater than some high
fixed value is larger than the fraction of molecules in sample N having kinetic energies
greater than that same high fixed value.

(E) The volume of sample M is twice the volume of sample N.
