HEAT CAPACITIES OF LIQUIDS - ESTIMATION OF HEAT CAPACITY AT CONSTANT PRESSURE AND 25 DEGREES C, USING ADDITIVITY RULES

Existing methods for estimating the heat capacity of liquids at constant pressure and 25° C. have a precision of not better than ±4 cal. mole-1 deg.-1. From previously measured data and the principle of group additivity, groups have been derived which enable heat capacities of liquids at constant pressure and 25° C. to be calculated to within ± 1.5 cal. mole-1 deg.-1 in all cases, and in most instances to better than ±1.0 cal. mole-1 deg.-1. © 1969, American Chemical Society.
