Question
A walrus transfers energy by conduction through its blubber at the rate of 150 W when immersed in $-1.00 ^\circ\textrm{C}$ water. The walrus’s internal core temperature is $37.0^\circ\textrm{C}$, and it has a surface area of $2.00 \textrm{ m}^2$. What is the average thickness of its blubber, which has the conductivity of fatty tissues without blood?
