thermostatics

noun

1. The part of thermodynamics that deals with reversible or infinitesimally small changes

   “Clearly, the entropy still has to be defined from thermostatics, and changes to S are attributed to the result of the NE fluctuation-dissipation theorem; Kim for instance has stated “the symmetric fluctuation associated with forward and backward manipulation of the NE work is contingent on time-reversal invariance of the underlying mesoscopic dynamics” which would lead to the ratio of the densities above to be unity.”
