A comparative study of ultrasonic velocity evaluated from Schaaffs collision factor theory (CFT), Nomoto relation, ideal mixing relation and Junjie relation has been carried out for the Pb-Sn alloy at three different temperatures and at various compositions. The agreement between experimental and theoretical values is quite satisfactory. The computed values of sound velocities from ideal-mixing relation have been used to obtain the degree of molecular interaction. Interaction studies have also been made in terms of excess intermolecular free-length and excess acoustic impedance.Full Text

Flory's statistical theory has been extended for the computation of internal pressure, isentropic compressibility, isothermal compressibility and Pseudo Gruneisen parameter of binary mixture nitrobenzene+benzene at pressure up to 10 MPa and at two different temperatures (293.15K, 303.15K & 313.15K). For a comparative study of the isothermal compressibility of this system, equation of state based on the psuedo spinodal hypothesis developed by Baonza et al has also been utilized to deduce the isothermal compressibility of this mixture. The computed values of Pint, βT, βs and Γ have been compared with the experimental findings available in literature. Satisfactory agreement has been found between experimental and theoretical values.Full Text

The Debye temperature has been computed for four quaternary mixtures over the entire range of composition at 298.15K. We have applied three different approaches and evaluated the Debye temperature using experimental data of ultrasonic velocity and density. This paper aims to portray the comparison of all the three approaches applied on the four quaternary mixtures which is being done for the first time to the best of authors knowledge .A good agreement is observed among the values computed with all the three approaches.Keywords
