Statistical Interpretation of Temperature and Entropy
... compared to any finite T entropy. If S contained a constant as well as the two terms in eq. (9.10) this constant would be the same for all systems, for the limit (eq. 9.11) is independent of the energy level spectrum and therefore of the type of system. Thus the value of this constant is physically ...

In the classical mechanics a motion is characterized by the position, velocity and acceleration. In thermodynamics on the other h ...

NOTES ON THERMODYNAMIC FORMALISM
... Interactions between systems are said to be reversible if they proceed infinitesimally slowly as a result of infinitesimal differences in temperature or pressure. Thus an infinitesimal change in the temperature of pressure of the systems would cause the interactions to occur in the opposite directio ...
