Seals may cool themselves by using thermal windows, patches on their bodies with much higher than average surface temperature. Suppose a seal has a 0.030 m^2 thermal window at a temperature of 30 degree C. If the seal’s surroundings are a frosty -10 degree C, what is the net rate of energy loss by radiation? Assume an emissivity equal to that of a human.
