The base plate of an iron has a thickness of L = 7 mm and is made from an aluminum alloy (p = 2800 kg/m³, c = 900 J/kg • K, k = 180 W/m K, & = 0.80). An elec- tric resistance heater is attached to the inner surface of the plate, while the outer surface is exposed to ambient air and large surroundings at Tx = Tsur = 25°C. The areas of both the inner and outer surfaces are A₁ = 0.040 m².
