Ultrasonic studies, densities and viscosities of binary liquid mixture of ethylamine and benzyl alcohol have been measured at different temperatures at 30ºC, 35ºC and 40ºC. The experimental value of speed of sound (u), isentropic compressibility (βs), intermolecular free length (Lf), viscosity (η), available volume (Va), molar volume (Vm) and...
