Isothermal compressibility studies of binary solution of cycloheptane and methanol

Abstract

Density and ultrasonic velocity data have been employed for the calculation of isothermal compressibility values (κT). Significance of the study of cohesive forces in the light of internal pressure has been emphasized during recent years. The internal pressure (Pi) and Pseudo-Gruneisen parameter (Γ) values have been computed by using the values of κT. The trend of variation in internal pressure and Pseudo-Gruneisen parameter reflects the disruption of molecular association due to a decrease in kinetic energy of constituents of solutions.
