Heat capacity and thermodynamic properties for coesite and jadeite, reexamination of the Tables of thermodynamic values for coesite and jadeite to K are presented. The entropies of coesite and jadeite are 6 and 6 J/(mol·K), respectively, at K. The entropy for coesite derived here confirms the value.

The experimental data were smoothed and estimates were made of heat capacities to K. The following equations represent our estimate of the heat capacities of coesite and jadeite between and K: [see original article for formula].
