Question

(a) What is the rate of heat conduction through the 3.00-cm-thick fur of a large animal having a 1.40-m^2 surface area? Assume that the animal's skin temperature is 32.0ºC, that the air temperature is -5.00ºC, 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?

Step 1

The thermal conductivity of air is approximately 0.024 W/m·K. The surface area is 1.40 m^2, the temperatures are 32.0°C (or 305.15 K) and -5.0°C (or 268.15 K), and the thickness is 3.00 cm (or 0.03 m). Substituting these values into the formula, we get: Q/t = Show more…
