In the diagram below, metal 1 is made of copper and metal 2 isaluminum. Both bars have the same length and area of cross-sectionbut their thermal conductivities are different. The temperature This maintained at a constant 88.0°C at the end A while thetemperature Tc at the end B is maintained at 35.0°C. There is awall on the left, labeled T_h, extending from that wall at a pointlabeled A is a metal cylindrical bar labeled metal 1. The metal 1cylinder meets flush against another metal cylinder labeled metal2. Where the two metal cylinders meet is a label T_j. The right endof metal 2 ends at a point labeled B against a wall with the labelT_C.
(a) What is the temperature Tj at the junction of the two bars?The thermal conductivity of copper is 390 J/(s · m · °C) and thatfor aluminum is 220 J/(s · m · °C). °C
(b) If metals 1 and 2 are now interchanged, but the values of Thand Tc are the same as in part (a), what will be the temperature ofthe junction
