First Law of Thermodynamics

The first law of thermodynamics, or conservation of energy, states that energy can be neither created nor destroyed, but only converted from one form to another. The motion of the molecules causes thermal or internal energy embodied within a system. Transient forms of energy include heat and work.

The first law of thermodynamics for a system undergoing a cycle is:

For the non-cycle process, the law is:


Q = The heat transferred to the system during the process

W = The work done by the system during the process E = Total energy of the system (internal, kinetic, and potential) in the given state (this energy may be associated with the motion and position of the molecules, with the structure of the atoms, with chemical reactions, with gravity, or with any of a number of other forms of interaction)
