The thermal conductivity of copper at room temperature is largely carried by the conduction e1etrorm, one per atom. The mean free path of the electrons at 300 K is of the order of 400 x 10–8 cm.
The conduction electron concentration is 13 x l022 per cm3. Estimate
(a) The electron contribution to the heat capacity;
(b) The electronic contribution to the thermal conductivity;
(c) The electrical conductivity. Specify units.
