Prof. Conlin wanted was curious if he could figure out the rate of heat transfer of his stove, in Joules/second. He decided he could measure it by heating up some water in a stainless-steel pot and boiling some water away. You're going to help him figure it out! First, he measured the mass of the pot without water in it, and got 0.906 kg. He measured the mass with 4 cups of water in it, and got 1.827 kg. That means the mass of the water is 1.827 kg - 0.906 kg = 0.921 kg Ozen (a) Heating up water. Prof. Conlin put it on the burner at 8:00am. It started boiling at 8:10am (600 seconds later. Calculate the amount of heat Qw in Joules it took to raise the temperature of the 0.921 kg of water from room temperature (20 C) to the boiling point of water (100 C). (b) Heating up steel pot. Calculate the amount of heat Q in Joules it took to raise the temperature of the stainless-steel pot from room temperature (20 C) to the boiling point of water (100 C). (c) Boiling away water. While the water was boiling, Prof. Conlin left it on the stove for 10 more minutes (600 more seconds). He measured the mass of the water and pot after the 10 minutes, and got only 1.665 kg. Calculate the amount of energy Q, in Joules, needed to boil away the missing mass of water. You can assume all of the heat went into changing the phase of the missing water (d) Rate of heat transfer. Calculate the average rate of heat transfer Q/t, in Joules per second, by finding the total heat transferred to the pot and water during whole 20-minute process, and dividing by the total time (1200 seconds)
