- - - - Volume thermal expansion coefficient,
        
        Volume compressibility of a solid,
    - - most solids in general Cp > Cv
      - but when T -> 0, Cp -> Cv
  - - - At room temperature, the value of the heat capacity is 3Nk = 3R per mole = 25 J/mol.deg
      - At lower temperatures the heat capacity drops markedly and approaches zero as T^3
  - - - This agrees with the Dulong-Petit law at high temperature, but fails at low temperature
- - - - Debye wavelength,
      - Debye temperature,
    - - describes the temperature dependence of the heat capacity not only at high temperatures but also at low temperatures
