WebEntropic definition, of or relating to entropy, a measure of the thermal energy unavailable for work, or of the constituent randomness, in a process or system: At very small scales, the entropic effects become significant, so a more intricate analysis, incorporating thermal fluctuations, is needed in the study of biopolymers. See more. WebThe 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 ΔS = Q/T.
