The First Law of thermodynamics is a formulation of the law of conservation of energy, adapted for thermodynamic processes. A simple formulation is: "The total energy in a system remains constant, although it may be converted from one form to another." Another common phrasing is that "energy can neither be created nor destroyed" (in a "closed system"). While there are many subtletie… WebThe first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic processes.
