WebWhether 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) Can affect heat flux by radiation through color and texture, which determine emissivity. Hevap: Heat lost by evaporation of body water. WebHeat loss happens when heat energy is exchanged between materials that are both at a two different temperature. There are different ways in which heat is lost they are: - conduction, convection, radiation and evaporation. All these processes can happen to heat. How am I going to carry out the investigation?
