Using a beater, you actively stir the water, doing work on the water. You observe that after 4 minutes, the water starts to boil (temperature 100C). From the manufacturer, you know that the electric pot uses 1200 W. Define the system to be the water. Current Attempt in Progress Part 1 Part 1 During this 4 minutes, what is the change in thermal energy of the water?
