Determination of specific thermal capacities depending on the temperature

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.
