Question 2

Two metal rods, one silver and the other gold, are attached to each other.
 
  The free end of the silver rod is connected to a steam chamber, with a temperature of 100C, and the free end of the gold rod to an ice water bath, with a temperature of 0C. The rods are 5.0 cm long and have a square cross-section, 2.0 cm on a side. What is the temperature at the point where the two rods are in contact with one another? The thermal conductivity of silver is 417 W/(mK) and that of gold is 291 W/(mK) No heat is exchanged between the rods and the surroundings, except at the ends. A) 39C
  B) 41C
  C) 47C
  D) 53C
  E) 59C
