Abstract

Thermo Excess acoustical parameters such as excess internal Pressure(πE), excess enthalpy (HE) and excess viscosity (ηE) have been measured from experimentally measured values of densities(), ultrasonic velocities(u) and viscosities(η) in binary liquid mixtures containing Ethylene Glycol with Ethanol at temperatures T=(298.15, 303.15, 308.15, 313.15 and 318.15) K. These results are fitted to the Redlich-Kister polynomial equation. These results have been explained on the basis of intermolecular interactions in liquid mixtures.
