Appendix E. Themodynamic Properties

E.1. Thermochemical Data

The heat capacity coefficients are used in the equation:

C_P = A + BT + CT² + DT³

where T is in K and C_P in J/mol-K The heat capacities tabulated on the back flap are only suitable for quick order of magnitude calculations. The full form of the heat capacity should be used when possible.

Note that the value of the heat capacity at room temperature is not given by the first coefficient A when other coefficients are present. The polynomial should not be truncated.
