A copper sheet having thickness of 2.25 mm is bonded to a steel sheet of thickness 1.29 mm. The outside surface of the copper sheet is held at a temperature of around 100.0°C and the steel sheet at 26.1°C.
i) Find out the temperature (in °C) of the copper-steel interface.
ii) Determine how much heat is conducted via 1.00 m2 of the joint sheets per second?
