Calculating Entropy of Some Solid Metals by Using n-Dimensional Debye Approximation

Abstract

The entropies of some solid metals have been analytically calculated by the use of n-dimensional Debye approximation in this study. The obtained formula is valid for all temperature ranges from low to melting temperature. We have compared our results with available numerical and experimental data for room temperature ( ). As can be seen that our results are in good agreement with literature.
