A copper rod, an aluminum rod, and a brass rod, each of6.00 m length and 1.00 cm diameter, are placed end to end with thealuminum rod between the other two. The free end of the copperrod is maintained at water’s boiling point, and the free end of thebrass rod is maintained at water’s freezing point. What is thesteady-state temperature of (a) the copper–aluminum junctionand (b) the aluminum–brass junction?
