Thermal energy is constantly being transferred from matter to the surrounding. The methods by which heat can be transferred are conduction, convection and radiation. Conduction is the transfer of energy from one object to another by contact and it will depends on factors such as surface area of the objects and thermal conductivity, k, is the property that indicates how good conductor of thermal energy is certain material (2). Convection is the transfer of energy due to a bulk motion of a fluid and can only be experimenter by liquids or gases (2). Finally, radiation is caused by the thermal motion of charged particles in matter (2). The current experiment will investigate the differences on the rate of heat transfer due to properties of different materials such as thermal conductivity and reflector and refractor properties. Moreover, this study will explore the regulation of thermal energy on an animal model and the effect of different conditions such as size or shape on the internal body temperature. In order to calculate heat transfer by conduction, the equation Q/t=(kA∆T_s)/d was used. Furthermore, Q=mc∆T_o was utilized to determinate the temperature change inside the animal models. Finally, when calculating area, mass and thickness of a cylindrical model it is necessary to use A=2πrh+πr^2, m=ρ(πr^2 h) and d=r respectively.
