‎First appearance of this joint paper in which further thermodynamical connections are published.Joule is well known for his discovery of Joule's Law, the connection between heat and mechanical work, where heat is a form of energy. ""In December of 1840 he presented a paper to the Royal Society on the production of heat by the electric current. His course of thought led him to the consideration of the relatio between heat and and mechanical work. The results of his investigations were embodied in a series of papers which culminated in his great memoir on the mechanical equivalent of heat, published in 1850. Joule was one of the founders of the principle of the cosservation of energy. Some of his work was done in collaboration with Lord Kelvin.""(Source Book in Physics p. 203).‎
