First rule of thermodynamics
WebThe first law of thermodynamics deals with the total amount of energy in the universe. It states that this total amount of energy is constant.

First rule of thermodynamics
Did you know?
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 applies the conservation of energy principle to systems where heat transfer and doing work are the methods of transferring energy into and out of the system.
