(from the article `thermodynamics`) The first law of thermodynamics asserts that energy must be conserved in any process involving the exchange of heat and work between a system and its ... ...energy is conserved provided that heat is taken into account. The irreversible nature of the transfer from external energy of organized motion to...

A fundamental law of physics, one form of which states that no device can completely and continuously transform all of the energy supplied to it into useful energy. See also second law efficiency.

Clausius' formulation of the second law states that heat cannot be transferred from a colder to a hotter body without some other effect, i.e. without work being done. Corollaries include the impossibility of converting heat entirely into work without some other effect, and the impossibility of perpe...

Type: Term Definitions: 1. the entropy of the universe moves toward a maximum; similarly, the entropy of any isolated microcosm (a chemical reaction) proceeds spontaneously only in that direction that yields an increase in entropy, entropy being maximal at equilibrium. To quote G.N. Lewis, 'Every process that occurs spontaneously is capable of doin...

This law states that heat can never pass spontaneously from a colder to a hotter body. As a result of this fact, natural processes that involve energy transfer must have one direction, and all natural processes are irreversible. This law also predicts that the entropy of an isolated system always increases with time.
