Factors Affecting Heat Loss.

... Science Investigation Factors Affecting Heat Loss Introduction: There are three main types of heat transfer, Convection, conduction and radiation. We are asked to do and experiment heat loss using one of the heat transfer. Our group chosen to do radiation because it would be a straight forward experiment and I understood the task of the experiment. We will be using Aluminium foil, both the shiny and matt sides, white colour paper, black colour paper and corrugated cardboard. Radiation: The hotter the object is the more heat energy it radiates. Different surfaces affect radiation. It depends an awful lot on surface colour and texture. Dark matt materials absorb the radiation falling on them. Much more strongly than bright glossy surfaces such as gloss white or silver. They also emit heat radiation much more to. Silvered surfaces reflect almost all heat radiation falling on them. Dark matt materials are poor reflectors and light surfaces are poor absorbers. Conduction: Conduction
