With the help of measured values of ultrasonic Velocity (U), density (ρ) and viscosity (η) excess acoustic and thermodynamic properties like velocity (UE), density (ρE), viscosity (ηE), adiabatic compressibility (βEa), free length (LEf), free volume (VEf), acoustic impedance (ZE), internal pressure (πEi), relaxation time (τE), Gibb’s free energy (GE) have been calculated for the binary mixture of isopropyl alcohol with CCl4, at various temperatures at a fixed frequency of 2 MHz for different concentration ranges. The graphs were plotted against the concentration of the mixture at different temperatures, from that the strength of interaction between like and unlike molecules has been discussed. |
