A Theoretical Study of the Compression Curves for NaCl

The compression curves for NaCl have been calculated using Birch-Murnaghan, Vinet, Misra-Goyal, Bardeen, Brennan-Stacey and the modified Lennard-Jones equations of state. The curves result from these equations of state have been compared with the results calculated from other theoretical methods based on Kumar equation. The variation of V/Vo with T at different pressures are calculated using Kumar equation to show the effect of P and T at the same time on V/Vo. The compression curves resulted from the used equations of state and Kumar equation at room temperature are plotted together with the experimental data of NaCl for the sake of comparison.
