A heat conducting rod, 0.90 m long, is made of an aluminum section, 0.10 m long, and a copper section, 0.80m long. Both sections have a cross-sectional area of 0.0004m^2 The aluminum end and the copper end are maintained at temperatures of 40C and 150C respectively. The thermal conductivities of aluminum and copper are 205 and 385 W/m ∙ K, respectively. The temperature of the aluminum-copper junction in the rod, in is closest in C to.
