Schottky Anomaly
... The Schottky anomaly is an observed effect in solid state physics where the specific heat capacity of a solid at low temperature has a peak ... It is called anomalous because the heat capacity usually increases with temperature, or stays constant ... difference between the energy levels there is a broad peak in the specific heat corresponding to a large change in entropy for a small change in temperature ...

But experiments at low temperatures showed that the heat capacity changes, going to zero at absolute zero ... As the temperature goes up, the specific heat goes up until it approaches the Dulong and Petit prediction at high temperature ...

Famous quotes containing the words heat and/or specific:

    Red river, red river,
    Slow flow heat is silence
    No will is still as a river
    —T.S. (Thomas Stearns)

    The more specific idea of evolution now reached is—a change from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity, accompanying the dissipation of motion and integration of matter.
    Herbert Spencer (1820–1903)
