Comparison of Three Temperature-Dependent Equations of State of Condensed Matter

Abstract

Considering temperature effects, we compare the equation of Vinet et al., the Birch equation and the K‐D equation with experimental data. The results show that the Birch equation is the best.

Volume and Temperature Dependence of the Second Gr�neisen Parameter of NaCl

“…The Birch equation, which is derived from the finit strain theory, is more accessible to reality than others [9]. For the present study we get h from the first-order Birch equation of the form (concerning thermal effects)…”
