Heat capacity of electrons and lattice atoms.
(a) At which temperature do the lattice atoms and the electrons in gold contribute
equally to the overall heat capacity.
(b) In what limits could we:
i. Ignore the electron contribution
ii. Ignore the lattice contribution
when calculating the overall heat capacity?
Note: Although Debye temperature can vary somewhat with temperature, we will
assume it is a constant value of θAu = 170K. (MAu = 170 g/mol, ρAu = 19.32
g/cm3); the concentration of conduction electrons in gold is N/V = 5.9×1022 cm−3
