Consider a small system that is interacting with a reservoir at temperature 400 K, pressure 108 Pa, and chemical potential ‒0.3 eV.

(a) To go from state 1 to state 2, the small system must take an additional 0.03 eV of energy and 10‒29 m3 of volume from the reservoir. How many times more probable is it for the small system to be in state 1 than state 2?

(b) To go from state 1 to state 3 the small system must take 0.4 eV of energy and one particle (but no extra volume) from the reservoir. How many times more probable is it that the small system is in state 1 than state 3?

(c) To go from state 1 to state 4, the small system must take no energy but one particle and 10‒27 m3 of volume from the reservoir. How many times more probable is it that the small system is in state 1 than state 4?
