Unformatted text preview: are based on rather rough approximations (anharmonicity is neglected, phonon spectrum is approximated by 2 in Debye model, etc.). In practice c p (T) in normally measured experimentally and the results are described analytically, e.g. C p = A + BT + CT-2 for a certain range of temperatures.
