Question
(a) What is the rate of heat conduction through the 3.00-cm-thick fur of a large animal having a $1.40\textrm{ m}^2$ surface area? Assume that the animal’s skin temperature is $32.0^\circ\textrm{C}$ , that the air temperature is $-5.00^\circ\textrm{C}$ , 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?
1. $39.7\textrm{ J/s}$
2. $820\textrm{ Calories}$
