WebThis occurs when a mammal sweats. Convection currents of air remove heat from the surface of dry skin as the air passes over it. Heat will be conducted from one surface to another during direct contact with the surfaces, such as an animal resting on a warm rock. Figure 2. Heat can be exchanged by four mechanisms: (a) radiation, (b) evaporation ... WebRadiation is heat gain or heat loss via radiation waves entering or leaving the body, particularly infrared waves. Conduction is the gain or loss of heat through direct contact with an object, for example, if a hot animal comes into contact with a cold rock, the rock will get warmer while the animal gets colder. Convection is heat gain or loss by

WebHrad: Heat emitted proportional to temperature in degrees K raised to 4 th power. Physics says all objects, living or dead, above 0oK radiate heat in this way. Whether radiation causes a gain or loss of heat depends on temperature of animal's surface relative to environment. (Overhead: Fig 16-19 - radiation vectors both ways)
