You are boiling water in an alumunum pot. The radius of the bottom of the pot is 10 cm and the aluminum is 3 mm thick. You find that when you put 0.9 kg of water into the pot, once it starts boiling the water will completely evaporate in 10 minutes. (HINT: The thermal conductivity of aluminum is 238 J/s m C.)
(a) What is the amount of energy required to turn all of the water into steam?
_____ J
(b) What is the temperature of the inner surface of the pot when the water is boiling?
_____ C
(c) What is the temperature of the outer surface of the aluminum pot when the water is boiling?
