14.5 Exercise 14

(a) What is the rate of heat conduction through the 3.00-cm-thick fur of a large animal having a $1 . \text{40}-\text{m}^{2}$ surface area? Assume that the animal’s skin temperature is $\text{32} . 0º \text{C}$, that the air temperature is $- 5 . \text{00}º \text{C}$, 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?
