Here we complete our discussion of the First Law and thermodynamic cycles.

Note on the definition of a "closed system." I am using the term "closed system" in the sense of the following definition from Thermal Physics by Charles Kittel: "A closed system is defined as a system with constant energy, constant number of particles, and constant volume." Another term for such a system is "isolated system," in which case "closed system" may refer to a system that has a constant number of particles but can exchange energy with its surroundings.
