25.
Electronic and lattice contributions to the specific heat of a
metal. Consider the relative size of the electronic and lattice contri-
butions to the specific heat of a metal using the Sommerfeld theory
for the electrons and the Debye model for the phonons. i. Find an
expression for the ratio c/c. i. Determine the temperature T* at
which cc. iii. Give an estimate on the order of magnitude for
T* in alkali metals.
