Suppose that a well-insulated room has a glass window that is 2.0 m high and 3.9 m wide. What is the rate of heat flow per second into the window from the environment outside if the temperature of the room is kept at 79.7o F and the outside temperature is 56.5o F? Assume that the glass is 0.33 cm thick, and express your answer in W.
