Two metal rods, one silver and the other copper, are both attached to a steam chamber as shown in the figure, with a temperature of 100°C, at one end, and an ice water bath, with a temperature of 0°C, at the other

The rods are 5.0 cm long and have a square cross-section, 2.0 cm on a side. When steady state has been reached, how much heat flows through the two rods in 1.0 min? The thermal conductivity of silver is 417 W/(m ? K), and that of copper is 395 W/(m ? K). No heat is exchanged between the rods and the surroundings, except at their ends. A) 20 kJ B) 39 kJ C) 47 kJ D) 49 kJ E) 11 kJ
