چکیده مقاله:
The major reason for the prediction of thermodynamic properties of mercury lies in the fact that itsintermolecular interactions highly depend on temperature and density. Internal pressure is a good criterion toinvestigate the density dependence of the interatomic interactions. Because its physical base is a forcetending to close together the molecules that is intermolecular interactions, and as well it can be calculatedfrom the experimental PVT data. In this study the behavior of the experimentally calculated internalpressure of the mercury demonstrates three different metallic, M-NMT and nonmetallic regions. Then toinvestigate these different states the general form of the Lennard-Jones potential function [LJ (m-n)] has beenchosen as the effective interaction potential and the experimentally calculated internal pressure has been usedto estimate the values of m and n in each state.
