HEAT CAPACITY MEASUREMENTS ON GELATIN GELS. II.

Abstract

Measurements of the heat capacity of gelatin gels, prepared from ash-free, electric gelatin, have been extended to cover the temperature range between − 180° and 25 °C. and the concentration range from 9 to 100% gelatin. Change in the temperature of the gel above the freezing point is found to be accompanied by a heat effect which has not previously been taken into account in calorimetric measurements on gels and which renders the interpretation of the experimental data uncertain.
