The constants a, b, c, and d are to be determined either experimentally or by some theoretical or semi-empirical approach The heat content, or enthalpy (H), is determined from the heat capacity by a simple integration of the range of temperatures for which the for- mula for cp is valid Thus, if 298K is taken as a reference temperature,
where all the constants on the right-hand side of the equation have been incorporated in the term –A.
In general, the enthalpy is given by a sum of terms for each phase of the substance involved in the temperature range considered plus terms that represent the heats of transitions:
In a similar manner, the entropy S is obtained by performing the integration

Values of these thermodynamic coefficients are given in the following tables The first column in each table lists the material The ond column gives the phase to which the coefficients are applicable The remaining columns list the values of the constants a, b, c, d, A, and B required in the thermodynamic equations All values that represent estimates are enclosed in parentheses The heat capacities at temperatures beyond the range of experimental determination were estimated by extrapolation Where no experimental values were found, analogy with compounds of neighboring elements in the periodic table was used
