Multifunctional Debye temperature acoustical and surface tension studies in combination of Ortho-xylene and Amyl acetate at four temperatures T (=303.15, 308.15, 313.15 to 318.15) K

Abstract

In the material mixture of Ortho-xylene and Amyl acetate over the complete mole fraction range of Ortho-xylene,basic acoustical parameters have been measured at different temperatures T = (303.15, 308.15, 313.15 and 318.15) K. From these basic measurements, Debye temperature and surface tension variation trends are studied. The variation trends of these parameters are observed to be increasing with mole fraction and decreasing with temperature which implies that there exist molecular interactions between the mixture. The molecular contribution with thermal energy fluctuations in binary liquid mixtures have been estimated. Debye temperature analogy, together with the differences in viscosity are carefully examined to explain molecular interactions between the constituent molecules of liquid mixtures.
