The coretemperature of the human body is 37.0 °C, and the skin, with a surface area of 1.40 m2, has a temperature of 34.0 °C. (a) Find therate of heat transfer out of the body under the following assumptions: (i) The average thickness of tissue between the core and theskin is 1.20 cm; (ii) the thermal conductivity of the tissue is that ofwater. (b) Without repeating the calculation of part (a), what rateof heat transfer would you expect if the skin temperature were tofall to 31.0 °C? Explain.
