The Dulong–Petit law, a thermodynamic law proposed in 1819 by French physicists Pierre Louis Dulong and Alexis Thérèse Petit, states the classical. Dulong–Petit law, statement that the gram-atomic heat capacity (specific heat times atomic weight) of an element is a constant; that is, it is the same for all solid elements, about six calories per gram atom. It is in fact that similarity of the molar specific heats of metals which is the subject of the Law of Dulong and Petit. Specific heat capacity data for a wide range of elements are used to assess the accuracy and limitations of the Dulong-Petit Law. Dulong and Petits Law || 11th Class || Mr.
