Abstract : A recently proposed equation of state is further examined for compatibility with prior theory. It is found, by adopting a more realistic functional relationship for one of the thermodynamic state variables and eliminating higher-order terms from the model, that three historical theories for determination of the Grueneisen function fall directly out of the recently proposed model. One is led to conclude that the newer model captures the essence of all of the older theories, each of which being applicable under an appropriate circumstance.
