Law of conservation of energy
Law of Conservation of energy or conservation of energy principle in thermodynamics states that the total heat or energy of our universe must remain constant. The relation between heat and work is the origin of the first law of conservation of energy. The first law of energy conservation in thermodynamics states that energy can neither be created nor be destroyed but may be transferred from one form to another. In other words, when one form of energy disappears, an exact and same amount of other form appears to maintain the net amount of energy in our universe. Hence a definite quantity of electrical energy is given to be equivalent quantity of heat or mechanical work.
In chemistry or physics, the conservation of energy principle provides the calculation and formula for specific heat change and transfer in cyclic, isothermal, isochoric, and isolated processes in terms of internal energy and work done by the system.
