Indicate whether each statement is true or false.

(a) The third law of thermodynamics says that the entropy of a perfect, pure crystal at absolute zero increases with the mass of the crystal.

(b) “Translational motion” of molecules refers to their change in spatial location as a function of time.

(c) “Rotational” and “vibrational” motions contribute to the entropy in atomic gases like He and Xe.

(d) The larger the number of atoms in a molecule, the more degrees of freedom of rotational and vibrational motion it likely has.
