摘要: The experimental data of density ( ρ ) and speed sound u in the temperature range (275.15 to 283.15) K have been obtained for aqueous solutions di-methyl sulphoxide (DMSO), ethylene di-amine (EDA), polyethylene glycol-200 (PEG-200) glycol-400 (PEG-400). specific heat C p DMSO, EDA, PEG-200 also at T = 279.15 K. are used calculate derived parameters like isentropic compressibility β S ), isothermal apparent molar volume ϕ V coefficient thermal expansion α KS internal pressure P i ). limiting values ∘ were obtained. From these data, coefficients properties computed. results interpreted terms solute–solvent solute–solute interactions structure making braking abilities solute. discuss extent hydrogen bonding between solute solvent (water).
