✦ Synopsis

In this paper the principle and theoretical basis of the step-heating technique for thermal diffusivity measurement is summarized. Application of two numerical fitting methods for data reduction-least-squares and Levenberg-Marquardt methods--is described. Results of thermal diffnsivity estimation from both simulated and experimental data are presented and discussed.

Enthalpies of dissolution, AHs, of malonic and malic acids in water have been determined at molalities ranging from 4 x 10 .3 to about 29 × 10 -3 for malonic acid and from 2 × 10 -3 to about 180 × 10 .3 for malic acid at 298.15K. These data are analysed taking into account an incomplete dissociation
