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… WebTemperature (in kelvin) is a measure of the average kinetic energy of molecules in an object. Heat is like mechanical work, in that an object cannot possess heat, but rather is acted upon by heat, changing the …
