Calorimetry
where c - specific heat capacity. The main measured value in a calorimetric experiment is ΔT. The methods of determination of the heat capacity of individual substances and physicochemical systems, heat of phase transitions, thermal effects of chemical reactions, dissolution, wetting, sorption, radioactive decay, etc. are determined by the methods of K. The data of K are used to calculate the thermodynamic properties of substances, to prepare thermal balances of technological processes, to calculate the chemical equilibrium, to establish a connection between the thermodynamic characteristics of substances and their properties, structure, stability, reactivity. K.
