چکیده
A descript ion is give n of apparatus employing a ce ll that is both a bellows dilatometer and a threeterminal elec t rode se t for measuring simu ltaneous ly the d e nsity and diel ec tri c properties of liquids as func tions of temperature and pressure . Measurement s are possible at temperatures from .1 20 oK to over 300 oK and pressures from 1 to 2000 atm with an uncertainty of 0.03 percent. The denSity, dlelectnc consta nt , and Clausius-Mossotti function of n-hexane have been m~asur.ed for temperat.ures from 2~3 to 298 oK (50 to 25 °C) and at pressures from 1 to 2000 atm. There IS a Imear decrease m the Clau.slUsMossotti function with density and a decrease with temperature correspondmg to an effecllve dipole moment of 0.085 debye.

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...
