1-65 An aluminum pan whose thermal conductivity is 237 W/m °C has a flat bottom with diameter 20 cm and thick- ness 0.4 cm. Heat is transferred steadily to boiling water in the pan through its bottom at a rate of 800 W. If the inner surface of the bottom of the pan is at 105°C, determine the temperature of the outer surface of the bottom of the pan.
