(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 32.0°C, that the air temperature is -5.00°C, and that fur has the same thermal conductivity as air. 

(b) What food intake will the animal need in one day to replace this heat transfer?
