The top layer of your goose down sleeping bag has a thickness of 5.0 cm and a surface area of . When the outside temperature is -20°C, you lose 25 Cal/h by heat conduction through the bag (which remains at a cozy 35°C inside). Assume that you’re sleeping on an insulated pad that eliminates heat conduction to the ground beneath you. What is the thermal conductivity of the goose down?
