The result is extremely simple; regardless of the nature of the crystal, the specific heat capacity (measured in joule per kelvin per kilogram) is equal to 3''R''/''MM'', where ''R'' is the Gas Constant (measured in joule per kelvin per mole) and ''MM'' is the Molar Mass (measured in kilogram per mole). In other words, the Dimensionless Heat Capacity is equal to 3. Despite its simplicity, Dulong-Petit law offers fairly good prediction for the specific heat capacity of solids with relatively simple crystal structure at high Temperature s. It fails, however, in the low temperature region, where the quantum mechanical nature of the solid manifests itself. There, the Debye Model works well. SEE ALSO |
