Concepts for specific heat
... The results is plotted in Fig. 1. In the case β~ω ≫ 1 (i.e. kB T ≪ ~ω) this becomes vanishingly small, while for β~ω ≪ 1 (i.e. kB T ≫ ~ω) we obtain the classical result kB . One says, that the degree of freedom freezes in around a temperature where kB T = ~ω. As the energies of the phonons for solid ...

... Example: Isobaric expansion of water One gram of water is placed in a cylinder, and the pressure is maintained at 2.0 x 105 Pa. The temperature is raised by 31 C. In one case, the water is in the liquid phase and expands by the small amount of 1.0 x 10-8 m3. In another case, the water is in the gas ...
