Two metal rods, silver and copper, are attached to a steam chamber with a temp 100 C, at one end and an ice bath ( 0 C ) at the other end. The rods are 25 cm long, square cross section 3 cm on a side. How much heat flows through the two rods in 60s? The thermal conductivty of silver and copper are 417 and 395 W/(mK), respectively. No heat is exchanged between the rods and the surroundings except at the ends.
