A rod of constant cross-sectional area has conductivity k1 and conducts heat at a constant rate between two reservoirs held at T1 and T2 respectively. It takes t1= 11.0-s to conduct Q= 32.5-J of heat across the rod. How much time would it take to conduct the same amount of heat if half the length of the rod were replaced with a material with conductivity k2=n·k1, where n= 3.7?
