Rod 1, with a thermal conductivity of 420 W/m-K, rod 2, with a thermal conductivity of 153 W/m-K, and rod 3, with a thermal conductivity of 137 W/m-K, are placed end to end with rod 2 between the other two. The rods have the same length and the same diameter. The free end of rod 1 is maintained at water's boiling point, and the free end of rod 3 is maintained at water's freezing point. What is the steady-state temperature of (a) the rod 1rod 2 junction and (b) the rod 2-rod 3junction?
