Debye Model - Debye Temperature Table

Debye Temperature Table

Even though the Debye model is not completely correct, it gives a good approximation for the low temperature heat capacity of insulating, crystalline solids where other contributions (such as highly mobile conduction electrons) are negligible. For metals, the electron contribution to the heat is proportional to, which at low temperatures dominates the Debye result for lattice vibrations. In this case, the Debye model can only be said to approximate for the lattice contribution to the specific heat. The following table lists Debye temperatures for several pure elements:

Aluminium 428 K
Beryllium 1440 K
Cadmium 209 K
Carbon 2230 K
Cesium 38 K
Chromium 630 K
Copper 343.5 K
Gold 170 K
Iron 470 K
Lead 105 K
Manganese 410 K
Nickel 450 K
Platinum 240 K
Silicon 645 K
Silver 215 K
Tantalum 240 K
Tin (white) 200 K
Titanium 420 K
Tungsten 400 K
Zinc 327 K

The Debye model's fit to experimental data is often phenomenologically improved by allowing the Debye temperature to become temperature dependent; for example, the value for water ice increases from about 222 K to 300 K as the temperature goes from Absolute zero to about 100 K.

Famous quotes containing the words temperature and/or table:

    The siren south is well enough, but New York, at the beginning of March, is a hoyden we would not care to miss—a drafty wench, her temperature up and down, full of bold promises and dust in the eye.
    —E.B. (Elwyn Brooks)

    How to attain sufficient clarity of thought to meet the terrifying issues now facing us, before it is too late, is ... important. Of one thing I feel reasonably sure: we can’t stop to discuss whether the table has or hasn’t legs when the house is burning down over our heads. Nor do the classics per se seem to furnish the kind of education which fits people to cope with a fast-changing civilization.
    Mary Barnett Gilson (1877–?)
