Iron with a power rating of 1200 watts is left on the ironing board. The convective heat transfer coefficient between the base surface and the surrounding air is 35 W/m2C°. If the base has an emissivity of 0.6 and a surface area of 0.02 m2, and the base is exposed to the air at 20°C, determine the temperature of the base of the iron.
