Rod 1, with a thermal conductivity of 373 W/m·K, rod 2, with a thermal conductivity of 292 W/m·K, and rod 3, with a thermal conductivity of 112 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 1-rod 2 junction and (b) the rod 2-rod 3 junction?
