Indicate whether each statement is true or false.

(a) Unlike enthalpy, where we can only ever know changes in H, we can know absolute values of S.

(b) If you heat a gas such as CO₂, you will increase its degrees of translational, rotational and vibrational motions.

(c) CO₂(g) and Ar(g) have nearly the same molar mass. At a given temperature, they will have the same number of microstates.
