A walrus transfers energy by conduction through its blubber at the rate of 150 W when immersed in −1.00 °C water. The walrus’s internal core temperature is 37.0 °C , and it has a surface area of 2.00 m2 . What is the average thickness of its blubber, which has the conductivity of fatty tissues without blood?
