3a) A moose with a surface area of 35 m2 is browsing on a 30C day. Its skin, protected by a 5-

cm thick coat, is at 25 C. The thermal conductivity of fur=0.03 W m1*K1. How much heat

does the moose lose due to conduction from its skin to the surrounding air?

3b) Explain at least three strategies this moose might use to conserve heat. What are the

advantages and disadvantages of each of the heat conservation strategies?
