Ultrasonic velocities, densities and viscosities have been measured in binary liquid mixture containing glycerol and Ethanol over the entire molefraction range of glycerol at temperatures T=(298.15,303.15,308.15,313.15 and 318.15)K. From experimentally measured data of ultrasonic velocity, density and viscosity, thermo-acoustical parameters such as adiabatic compressibility(?), intermolecular freelength(Lf), acoustical impedance(Z) and internal pressure(?) have been calculated. These results have been explained in terms of molecular interactions.
