A hiker is wearing wool clothing of 0.60 cm thickness to keep warm.Her skin temperature is 33° C and the outside temperature is 2.0°C. Her body surface area is 1.2 m2.
(a) If the thermal conductivity of wool is 0.040 W/(m · K), what isthe rate of heat conduction through her clothing? in W
(b) If the hiker is caught in a rainstorm, the thermal conductivityof the soaked wool increases to 0.60 W/(m · K) (that of water). Nowwhat is the rate of heat conduction? in W.
