Abstract
Thermo-acoustical parameters of liquid mixtures viz., Acetone, Methyl Iodide and Acetone + Methyl Iodide have been evaluated at different temperatures in terms of the coefficient of volume expansion, on the assumption that the Moelwyn–Hughes parameter has been utilized to establish some simple relations between the lattice Gruneisen parameter, Beyer's non-linearity parameter, the Anderson–Gruneisen parameter and the Sharma constant. A relationship among the isobaric, isothermal and isochoric microscopic (lattice) Gruneisen parameters have been studied and analysed in the case of liquid mixtures. The Sharma's parameter S 0 remains invariant with the temperature over a wide range of temperatures and retains its characteristics value i.e., 1.11 ± 0.01 as observed in case of liquid systems. The present treatment has the distinct advantage of calculating available volume ( V a) and intermolecular free-length ( L f) through Moelwyn–Hughes parameter mainly. Analysis of such type is not found so far in literature.
