The top layer of your goose down sleeping bag has a thickness of 5.1 cm and a surface area of 1.0 m^2 . when the outside temperature is -19 c you lose 26 cal/hr 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?
