Consider a room that is initially at the outdoor temperature of 20°C. The room contains a 18 W lightbulb, a 81W TV set, a 87 W refrigerator, and a95 W iron. Assume no heat transfer through the walls. By applying the rate form of the energy balance,determine the rate of increase of the-energy content of the room when all of these electric devices are on. Give-your answer in W to 0 decimal place.
