Thermodynamic Relations (simple compressible systems) The functions: p-v-T pressure, volume, temperature (eqs of state) e energy (internal, kinetic and potential) u internal energy h enthalpy (u + pv) s entropy ψ = u – Ts Helmholtz function g = h – Ts Gibbs function The state principle: for a simple compressible system the values of two, independent intensive properties define the state of the system. Principle exact differentials (Gibbs relations): du(s,v) = Tds – pdv dh(s,p) = Tds + vdp d ψ (T,v) = - sdT – pdv
