ENERGY ONLY CHANGES FORMS; IT IS NEVER CREATED OR DESTROYED.

  • Maxwell’s demon is a thought experiment created by the physicist James Clerk Maxwell in 1867 in which he suggested how the second law of thermodynamics might hypothetically be violated.[1] In the thought experiment, a demon controls a small door between two compartments of gas. As individual gas molecules approach the door, the demon quickly opens and shuts the door so that only fast molecules are passed into one of the chambers, while only slow molecules are passed into the other. Because faster molecules are hotter, the demon’s behavior causes one chamber to warm up and the other to cool down, thereby decreasing entropy and violating the second law of thermodynamics. This thought experiment has provoked debate and theoretical work on the relation between thermodynamics and information theory extending to the present day. Several scientists argue that theoretical considerations rule out any practical device violating the second law in this way.
  • The First Law of Thermodynamics (Conservation) states that energy is always conserved; it cannot be created or destroyed. In essence, energy can be converted from one form into another.  ENERGY ONLY CHANGES FORMS; IT IS NEVER CREATED OR DESTROYED.
