Consider a room that is initially at the outdoor temperature of 20oC. The room contains a 40-W lightbulb, a 86-W TV set, a 319-W refrigerator, and a 1,339-W iron. Assuming no heat transfer through the walls, determine the rate of increase of the energy content of the room when all of these electric devices are on.
