Overview
ABSTRACT
Thermal capacity is an essential tool for the calculation of thermodynamic quantities. It can be determined at constant pressure Cp or at constant volume Cv. Where it is "specific" (cp or cv), it can be mass or molar. There is no confusion when using mass thermal capacity; however, molar thermal capacities can lead to confusion if the mole has not been defined. For example, the compound Sb2Te3 can also be written Sb.4Te.6. In general, when working with metal alloys, it is advisable to bring all the coefficients to one mole of atoms.

INTRODUCTION
The heat capacity is an essential tool for calculating thermodynamic quantities. It can be determined at constant pressure C p or constant volume C v . When it is said to be "specific" (c p or c v ), it can be mass or molar. There is never any confusion when using mass heat capacities, on the other hand molar heat capacities can lead to confusion if the mole has not been defined. For example, the compound Sb 2 Te 3 , can also be written as Sb .4 Te .6 . As a general rule, when working with metal alloys, it's best to reduce all coefficients to one atomic mole.
