Two metal rods connected between identical thermal reservoirs.
Two metal rods connected between identical thermal reservoirs.
A solid metal rod of length \(L\) and cross-sectional area \(A\) conducts energy at a steady rate \(P_0\) between two thermal reservoirs maintained at constant temperatures \(T_H\) and \(T_C\), with \(T_H > T_C\). A second rod, made of the same metal, has a length of \(2L\) and a cross-sectional area of \(2A\). If the second rod is connected between the same two thermal reservoirs, what is the rate of energy transfer through the second rod?
