Two pots are identical except that the flat bottom of one is aluminum, whereas that of the other is copper. Water in these pots is boiling away at 100.0 ˚C at the same rate. The temperature of the heating element on which the aluminum bottom is sitting is 153 ˚C. Assume that heat enters the water only through the bottoms of the pots and find the temperature of the heating element on which the copper bottom rests.

Two pots are identical except that the flat bottom of one is aluminum, whereas that of the other is copper. Water in these pots is boiling away at 100.0 °C at the same rate. The temperature of the heating element on which the aluminum bottom is sitting is 169 °C. Assume that heat enters the water only through the bottoms of the pots and find the temperature of the heating element on which the copper bottom rests. Tcu = i

Consider two cooking pots of the same dimensions, each containing the same amount of water at the same initial temperature. The bottom of the first pot is made of copper, while the bottom of the second pot is made of aluminum. Both pots are placed on a hot surface having a temperature of 130 C. The water in the copper-bottomed pot bols away completely in 525 s. How long does it take the water in the aluminum-bottomed pot to boil...

Page < > of 2 1) When shopping for cooking pots, pots whose bottoms have high thermal conduetivity (e.g. copper) command a higher price, since they will conduct heat the fastest. However the pots with the thickest bottoms also usually command a higher price. That may be counter-intuitive, since a thicker pot bottom means more resistance to heat transfer from the stove flame to the food inside the pot. How significant is this resistance? Show this quantitatively for a 10"...

QUESTION 6 (100 marks) An aluminum pan whose thermal conductivity is 237 W/m. °C has a flat bottom with diameter 20 cm and thickness 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, figure 4. STAR 0.4 cm 800 W Figure (4)
