Callen (1960) has shown that the intensive parameters of a thermodynamic system can be written as functions of the extensive variables; that is T = T(S,V,N), P = P(S,V,N), and µ = µ(S,V,N). These expressions are called equations of state Splet07. mar. 2011 · Snapshots Details The main thermodynamical variables are energy , enthalpy , free energy of Helmholtz , free energy of Gibbs , entropy , temperature , pressure , and volume .
