Entropy (arrow of time) — Entropy is the only quantity in the physical sciences that picks a particular direction for time, sometimes called an arrow of time. As one goes forward in time, the second law of thermodynamics says that the entropy of an isolated system can… … Wikipedia
Entropy (classical thermodynamics) — In thermodynamics, entropy is a measure of how close a thermodynamic system is to equilibrium. A thermodynamic system is any physical object or region of space that can be described by its thermodynamic quantities such as temperature, pressure,… … Wikipedia
Entropy (order and disorder) — Boltzmann s molecules (1896) shown at a rest position in a solid In thermodynamics, entropy is commonly associated with the amount of order, disorder, and/or chaos in a thermodynamic system. This stems from Rudolf Clausius 1862 assertion that any … Wikipedia
Entropy of mixing — The entropy of mixing is the change in the configuration entropy, an extensive thermodynamic quantity, when two different chemical substances or components are mixed. This entropy change must be positive since there is more uncertainty about the… … Wikipedia
entropy — entropic /en troh pik, trop ik/, adj. entropically, adv. /en treuh pee/, n. 1. Thermodynam. a. (on a macroscopic scale) a function of thermodynamic variables, as temperature, pressure, or composition, that is a measure of the energy that is not… … Universalium
Entropy and life — Much writing has been devoted to Entropy and life. Research concerning the relationship between the thermodynamic quantity entropy and the evolution of life began in around the turn of the 20th century. In 1910, American historian Henry Adams… … Wikipedia
Fanno flow — refers to adiabatic flow through a constant area duct where the effect of friction is considered. Compressibility effects often come into consideration, although the Fanno flow model certainly also applies to incompressible flow. For this model,… … Wikipedia
