WebApr 7, 2024 · The concept of entropy was first introduced in 1850 by Clausius as a precise mathematical way of testing whether the second law of thermodynamics is violated by a particular process. The test begins with the definition that if an amount of heat Q flows into a heat reservoir at constant temperature T, then its entropy S increases by Δ S = Q / T. WebMar 24, 2024 · Entropy. In physics, the word entropy has important physical implications as the amount of "disorder" of a system. In mathematics, a more abstract definition is used.
