ON THEORIES OF THE GRUNEISEN-PARAMETER

A recently proposed equation-of-state is examined further for compatib ility with prior theory. It is found, by adopting a more realistic fun ctional relationship for one of the thermodynamic state variables and eliminating higher-order terms from the model, that three historical t heories for determination of the Gruneisen 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 is applicable under an appropriate circumstance.
