WebCounter-current Heat Transfer Even when penguin feet are in contact with frozen surfaces, they don’t freeze. Pumping warm blood through their feet would cause the heat to radiate … WebThe dark body part of the penguin absorbs heat from the sun which helps them to remain warm. The gland near the tail provides a coat of oil to feathers to increase their water-resistant power. Feathers are not much helpful underwater because the temperature of the sea is -2.2 0 C, so it is difficult to waterproof. WebTheir stance has adapted in such way to minimize heat loss. They stand on 3 resting points: their 2 heels, and tail. The plantar surfaces of their feet do not touch the ground, minimizing heat loss to the ground. The rest of their body is situated in such way to prevent freezing. cummins isx oil pump location
