Removing the mystery of entropy and thermodynamics . Part 3

In Part 3 of this five-part article,[1, 2] simple graphic properties of entropy are illustrated, offering a novel way to understand the principle of entropy increase. The Boltzmann entropy is introduced and shows that in thermal equilibrium, entropy can be related to the spreading of a system’s occupied microstate over accessible microstates. Finally, constant-temperature reservoirs are shown to be idealizations that are nevertheless useful. A question-answer format is continued here and Key Points 3.1 3.4 are enumerated.
