Analytical study of thermodynamic quantities with surface tension and Debye temperature variations in Quinoline & p-Xylene at T=303.15 K to 318.15 K

Thermo dynamic physical quantities viz., compressibility (beta), molecular free length (L-f) and impedance (Z) are calculated in the binary organic liquid mixture having Quinoline + p-Xylene at temperatures T = 303.15 K to 318.15 K with 5 K variation using experimentally measured ultrasonic velocities, densities and viscosities with the molar concentration of Quinoline. Theoretical estimations are used to calculate Debye temperature and Surface tension in the above liquid mixture at different temperatures. A correlation of Surface Tension and Debye Temperature with the thermodynamic physical quantities are examined to bring out the inclusion of structural changes occurred due to the temperature variations in the aforesaid binary mixture. The output data is analysed the molecular association and to discuss component molecules structural behaviour with the temperature in the binary organic liquid mixture. (C) 2021 Elsevier Ltd.
