Thermodynamic Relations and Functional Forms for Equations of State
Both historical and current functional forms for equations of state used for properties of cryogens are described in this chapter. This includes pressure-explicit equations of state and fundamental equations with the Helmholtz energy as the dependent variable. (Pressure-explicit equations of state require an independent function for the heat capacity as a function of temperature.) Reference states are defined for enthalpy and entropy.
