Equal to the number of microstates in a system times Boltzmann's constant, this quantity can also be expressed as the amount of energy in a system unavailable to do work.
Shannon's version of this quantity applies to information systems. Equal to the number of microstates in a system times Boltzmann's constant, this quantity can also be expressed as the amount of energy in a system unavailable to do work. A thought experiment called Maxwell's Demon supposedly (*) decreases this value, even though this value is always increasing in the universe according to the Second Law of Thermodynamics. Symbolized by capital S, name this measure of disorder in a system.
Shannon's version of this quantity applies to information systems.
