The heat theorem was formulated in 1906 by German physical chemist Walther Nernst. [2] In the years to follow, Nernst's heat theorem was molded into the third law of thermodynamics by German physicist Max Planck, which he used as a founding principle for his "quantum theory", along with his earlier usage of Boltzman's second law based idea of the equipartition of the energy of bodies into distinct units, i.e. energy elements, which formed the basis for the science of

Third law

The heat theorem became the “third law”, of thermodynamics, in agreed upon namesake, sometime between 1907 and 1923. [3] Nernst’s heat theorem was being called a “new law of thermodynamics” (Otto Sackur, 1910), new “principle of thermodynamics” (Max Planck, 1910), and somewhere in his own lectures, Nernst had become his theorem the third law.
