“…Due to the scarcity of experimental data, the effective Debye temperature of liquid metal alloys could not be calculated. However, using ultrasonic speed, density and heat capacities ratio, recently (Shukla, et al, 2007), θD has been computed for Sn-Pb alloy at different temperatures. In the present work, we are extending the calculation of θD to two alloys, namely K-Rb and Na-Cs at different temperatures.…”

On the basics of quasicrystaline structure of liquid state Debye temperature, θD of two liquid metal alloys K-Rb and Na-Cs has been calculated at different temperatures ranging from (298.15-523.15) K and varying composition of alloys. Ultrasonic speed (u), density (ρ) and heat capacities ratio (γ) are the only data needed. Theoretical values have been compared with the standard finding and quite good agreement has been achieved. Experimental data of ρ, u and γ were taken from the literature. The negative values of ∆θD obtained are attributed to the decrease of short range order in the mixture compared to the order prevailing in pure liquid indicating less compression in mixture as compare to individual component. The mole ratios also affect the Debye temperature by decreasing its value with increase in the composition of the first component of the above two liquid metal alloys.

“…This property is related to thermodynamic properties such as molecular weight [4], molecular radius [5], surface tension [6], structure and dynamics of interface [7], molecular magnetic rotation [8], pseudo-Gruneisen parameters [9] and intermolecular free length [10]. The isochoric heat capacities and sound velocities have been extensively tabled for different fluids [11][12][13][14][15][16][17][18].…”

Investigation on the molecular interactions between binary mixtures containing diethyl carbonate in combination with nitrobenzene, chlorobenzene and aniline is presented. Ultrasonic velocity and density values were determined for the individual components as well as binary mixtures of the above benzene derivatives with diethyl carbonate at temperatures (293.15, 298.15, 303.15, 308.15, 313.15, 318.15 and 323.15) K over the entire composition range. Further, adiabatic compressibility and acoustic impedance values were calculated using the experimental results. In addition to these parameters, the excess parameters like excess adiabatic compressibility, excess acoustic impedance and deviation in ultrasonic velocity were also obtained. Based on all these results, molecular interactions among the selected components were discussed.
