  What will be an ideal response?

Question 2

Two metal rods, one silver and the other copper, are both immersed at one end in a steam chamber at a temperature of 100C.
 
  The other end of each one is in an ice water bath at 0C. The rods are 5.0 cm long and have a square cross-section that is 2.0 cm on a side. No heat is exchanged between the rods and the surroundings, except at the ends. How much total heat flows through the two rods each minute? The thermal conductivity of silver is 417 W/m  K, and that of copper is 395 W/m  K.
  A) 49 kJ B) 11 kJ C) 39 kJ D) 20 kJ E) 47 kJ
