Le Chatelier's Principle - Status As A Physical Law

Status As A Physical Law

Le Chatelier's principle qualitatively describes systems of non-instantaneous change; the duration of adjustment depends on the strength of the negative feedback to the initial shock. Where a shock initially induces positive feedback (such as thermal runaway), the new equilibrium can be far from the old one, and can take a long time to reach. In some dynamic systems, the end-state cannot be determined from the shock. The principle is typically used to describe closed negative-feedback systems, but applies, in general, to thermodynamically closed and isolated systems in nature, since the second law of thermodynamics ensures that the disequilibrium caused by an instantaneous shock must have a finite half-life. The principle has analogs throughout Systems theory.

Famous quotes containing the words status as, status, physical and/or law:

    As a work of art it has the same status as a long conversation between two not very bright drunks.
    Clive James (b. 1939)

    Knowing how beleaguered working mothers truly are—knowing because I am one of them—I am still amazed at how one need only say “I work” to be forgiven all expectation, to be assigned almost a handicapped status that no decent human being would burden further with demands. “I work” has become the universally accepted excuse, invoked as an all-purpose explanation for bowing out, not participating, letting others down, or otherwise behaving inexcusably.
    Melinda M. Marshall (20th century)

    I was always a feminist, for I liked intellectual revolt as much as I disliked physical violence. On the whole, I think women have lost something precious, but have gained, immeasurably, by the passing of the old order.
    Ellen Glasgow (1873–1945)

    The due process of law as we use it, I believe, rests squarely on the liberal idea of conflict and resolution.
    June L. Trapp (b. 1930)
