A copper sheet of thickness 2.19 mm is bonded to a steel sheet of thickness 1.13 mm. The outside surface of the copper sheet is held at a temperature of 100.0°C and the steel sheet at 25.7°C.
a) Determine the temperature (in °C) of the copper-steel interface.
b) How much heat is conducted through 1.00 m2 of the combined sheets per second?
