(a) What is the rate of heat conduction through the 3.00-cm-thick fur of a large animal having a 1.40-m2 surface area? Assume that the animal’s skin temperature is 32.0ºC , that the air temperature is −5.00ºC , and that furhas the same thermal conductivity as air.                                                            (b) What food intake will the animal need in one day to replace this heat transfer?

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.

A window has dimensions of 1 m by 2.6 m and is made of glass 6 mm thick. On a winter day, the outside temperature is 24° C while the inside temperature is a comfortable at 16° C. (k of glass =0.095W/m.K) Calculate the following: a) the area of the window in square metres b) the temperature gradient (AT/Ax)in kelvin/metre c) the rate of heat lost through the window by conduction in watts/metre.kelvin
