Question
Indicate whether each statement is true or false. (a) The
third law of
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.
