The excess values of the molar adiabatic compressibility as well as adiabatic compressibility coefficeint were estimated for binary mixtures of 1,2-ethanediol+1-pentanol at the temperatures (293.15, 303.15, 308.15 and 313.15) K. Alsko deviations of the ultrasonic speed from the chosen additivity rules were determinated. Together with the previous result for T = 298.15K (E. Zorębski, Mol.Quant Acoust.,24 261-270 (2003)), the effect of temperature on speed of ultrasound and adiabatic compressibility is studied. It appears that both excesses decrease with increasing temprature whereas deviations of ultrasonic speed have opposite temperature dependencies.
