39. (II) A copper rod and an aluminum rod of the same length and cross-sectional area are attached end to end (Fig. 14-18). The copper end is placed in a furnace maintained at a constant temperature of 250C. The aluminum end is placed in an ice bath held at constant temperature of 0.0C. Calculate the temperature at the point where the two rods are joined. Cu A1 250C 7'=? 0.0C
