Title

COMMON INTERSECTION POINTS IN DENSE FLUIDS VIA EQUATIONS OF STATE

Pages

  301-310

Abstract

 Some new equations of state which are derived for dense fluids in recent years, namely the linear isotherm regularity (LIR), the dense system EQUATION OF STATE (DSEOS), Ihm-Song-Mason EQUATION OF STATE (ISM), and a newly derived semi- emperical EQUATION OF STATE have been used to investigate the COMMON INTERSECTION POINT of ISOBARIC EXPANSIVITY (αp) in dense fluids. We have shown that the accuracy of these equations of state in predicting such a COMMON INTERSECTION POINT is reduced from the new semi-imperical EQUATION OF STATE, DSEOS, LIR, to ISM Respectively.Form physical point of view, the van der Waals EQUATION OF STATE is used to investigate such an intersection point. It is shown that the van der Waals repulsion forces and temperature dependency of the effective molecular diameter are important for existence of this common point.Finally, we have shown that the COMMON INTERSECTION POINTs of the isotherms of thermal pressure coefficient, the isotherms of heat capacity at constant volume, and the isochors of internal pressure for a fluid are related to each other. Also, the COMMON INTERSECTION POINTs of the reduced bulk modulus and 1/(Tαp) for isotherms of a fluid both appear at the same density.
