A30 kg male emperor penguin under a clear sky in the bio antarctic winter loses very little heat to the environment by convection; its feathers provide very good insulation. it does lose some heat through its feet to the ice, and some heat due to evaporation as it breathes; the combined power is about 12 w the outside of the penguin's body is a chilly -22°c, but its sur- roundings are an even chillier -38°c. the penguin's surface area is 0.56 m2, and its emissivity is 0.97. a. what is the net rate of energy loss by radiation? b. if the penguin has a 45 w basal metabolic rate, will it feel warm or cold under these circumstances?
