1.6 Exercise 26

(a) What is the rate of heat conduction through the 3.00-cm-thick fur of a large animal having a $1.40 -\text{m}^{2}$ surface area? Assume that the animal’s skin temperature is $32.0 ° \text{C}$, that the air temperature is $−5.00 ° \text{C}$, 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?
