A skier wears a goose down jacket of thickness 3.75cm and total surface area of 1.25m^2. The rate at which heat is conducted from the skin to the outside surface of the down is 41.67W. If the temperature at the surface of the clothing is -16.0degrees Celcius, determine the temperature at the surface of the skin. (Thermal conductivity of goose down = 0.025 (J/(s.m.degree Celcius))
