The Physics and Mathematics of the Second Law of Thermodynamics by Elliott H. Lieb, Jakob Yngvason
Publisher: arXiv 1999
Number of pages: 101
The essential postulates of classical thermodynamics are formulated, from which the second law is deduced as the principle of increase of entropy in irreversible adiabatic processes that take one equilibrium state to another. Temperature is derived from entropy, but at the start not even the concept of 'hotness' is assumed.
