The proper definition of entropy is fundamental to the relationship between statistical mechanics and thermodynamics. It also plays a major role in the recent debate about the validity of the concept of negative temperature. In this paper, I analyze and calculate the thermodynamic entropy for large but finite quantum mechanical systems. A special feature of this analysis is that the thermodynamic energy of a quantum system is shown to be a continuous variable, rather than being associated with…

The postulates for thermodynamics are examined critically, and some modifications are suggested to allow for the inclusion of long-range forces, inhomogeneous systems with non-extensive entropy, and systems that can have negative temperatures.

Gibbs’ Paradox is shown to arise from an incorrect traditional deﬁnition of the entropy that has unfortunately become entrenched in physics textbooks, which predicts a violation of the second law of thermodynamics when applied to colloids.
