Review of classical thermodynamics
... A state function, called the internal energy, exists for any physical system – and the change in the internal energy during any process is the sum of work done on/by the system and heat transferred to/from the system. ΔU = q – w or in differential form: dU = δq - δw U – internal energy (all potentia ...

Conservation of energy
In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can be neither created nor be destroyed, but it transforms from one form to another, for instance chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind cannot exist. That is to say, no system without an external energy supply can deliver an unlimited amount of energy to its surroundings.
