Suppose you warm up 470 grams of water (about half a liter, or about a pint) on a stove, and while this is happening, you also stir the water with a beater, doing 4104 j of work on the water. after the large-scale motion of the water has dissipated away, the temperature of the water is observed to have risen from 25â°c to 76â°c. what was the change in the thermal energy of the water?
