A student is sleeping under a small goose-down comforter that has coefficient of thermal conductivity of 0.025 W/m °C. The thickness of the down comforter is 5.0 cm and the area of the comforter is 2.0 m2. If the temperature difference between inside of the comforter and the outside of the comforter 40°C, then what is the rate of heat flow through the comforter?
