1. The problem statement, all variables and given/known data elephants have large ears because they need additional skin to balance the large amount of mass (to balance the heat eleminated from their skin with the heat generated by their body mass) by which methods of heat transfer do the ears eliminate excess body heat? 3. The attempt at a solution radiation would be an obvious choice, but im wondering if it would be more accurate to say Convection and Radiation . any thoughts?
