摘要:

A new statement of the second law of thermodynamics is given. The law leads almost effortlessly, for very general closed systems, to a definition of absolute entropyS, a demonstration that ΔS≥0 in adiabatic processes, a definition of temperature, and a demonstration thatdS≥δQ/Tin quasistatic processes. Entropy is given a clear physical meaning.
