The 5-mm-thick bottom of a 200-mm-diameter pan may be made from aluminum (k = 240 W/m-K) or copper (k = 390 W/m-K). When used to boil water, the surface of the bottom exposed to the water is nominally at 110°C and heat is transferred from the stove to the pan at a rate of 900 W. What is the temperature of the surface in contact with the stove for each of the two materials? Aluminum: T = Copper: T = °℃ °℃
