چكيده فارسي :
An analytical expression based on the linear isotherm regularity is derived for thermal pressure coefficients (TPC) of dense fluids using the intermolecular force theory to be valid for liquid Cs. The parameters of the linear isotherm regularity, the so-called LIR equation of state, are used to calculate the TPC of dense fluids. In this way, the temperature dependence of LIR parameters in the form of first order have been developed to second order and third order, and the temperature derivatives of LIR parameters are used to calculate TPC. The results obtained predict accurately TPCs for the densities high than the Boyle density and at temperature below twice the Boyle temperature.
