A deer has a skin temperature is $32\mathrm{.}0$C$,$ the air temperature is $-5\mathrm{.}00$C$.$

Assuming the deer$$s fur has the same thermal conductivity as air of $0\mathrm{.}023$ J

s$$m$$K :

a $()$ What is the rate of heat conduction through the $3\mathrm{.}00$ cm thick fur with a $1\mathrm{.}40$ m$2$

surface area?

b $()$ What food intake will the animal need in one day to replace this heat transfer
