The 10-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 ata rate of 900W. What is the temperature of the surface in contact with the stove for each of the two materials?

Question
The 10-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 =
i
°C
Copper:
T =
i
°C
