Assume that at low temperatures only the lattice vibrations and the electrons treated as a Fermi gas contribute to the heat capacity of a metal. The heat capacity of silver, measured at a temperature of 4 K, is 0.0134 J/(mole ·K). The Debye temperature of silver is 225 K. What are the electronic contribution (J/(mole ·K)) to the heat capacity of silver at 2 K?
