Dulong & Petit law Early in the 19 th century, two French scientists announced a law that would eventually be named after them. The law of Dulong and Petit deals with the heat capacities of elements. Later in the 19 th century it would prove to be helpful in clarifying atomic weights and atomic formulas. The table below contains the data on which Dulong and Petit based their law.
