== A bar of aluminum (bar A) is in thermal contact with a bar of copper (bar B) of the same length and area (see the figure below). One end of the compound bar is maintained at T = 78.5C, and the opposite end is at 30.0C. Find the temperature at the junction when the energy flow reaches a steady state.
