Problem
Two chunks of metal with heat capacities C1 and C2 are interconnected by a rod of length l, cross-sectional area A, and thermal conductivity k. The whole system is thermally insulated from the environment. At time t=0, the temperature difference between the chunks is (ΔT)0. Assuming the heat capacity of the rod is negligible, find the temperature difference between the chunks as a function of time.
