Two metal rods, one silver and the other copper, are both attached to a steam chamber, 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. How much heat flows through the two rods in 60 s? 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 the ends.
A) 20 kJ
B) 39 kJ
C) 47 kJ
D) 49 kJ
E) 11 kJ
