2-70 A 1000-W iron is left on the ironing board with its base exposed to the air at 23°C. The convection heat transfer coefficient between the base surface and the surrounding air is 35W/m2 °C. If the base has an emissivity of 0.9 and a surface area of 0.02 m², determine the temperature of the base of the iron.
