Examples of this include stirring liquid in a pot or when a convection oven uses a fan and exhaust system to blow hot air over and around the food before venting it back out. Three main types of conduction are: electric conduction, ionic conduction, and thermal conduction. The atoms in the colder object start to move faster, spreading that heat energy around, warming the object up. In the case of a steel band or heavy mesh band, the heat transfer to the base of thedough piece is solely by conduction. But, at the end of the day, induction is nothing more than a more recent and efficient heat transfer method than conduction. Also, we will keep the sides of the bar insulated so that no heat transfer occurs between the surroundings. Thus it is evident that the heat flows along the length of the rod. Conclusion: In fluids, such as water and air, convection is a much more efficient method of heat transfer than conduction. Conduction is the transfer of thermal energy between neighbouring molecules within anobject or between objects in contact with each other. 10.Green house trap heat that is radiated by the ground or the objects below it. Moreover, the expansion of a material due to heating depends on thermal conductivity. Glass also makes for excellent bakeware for infrared cooking because it allows some infrared light to pass through, hitting the surface of the food inside it and therefore cooking that food faster. It will be seen that this convection system only affects the surface of the dough piece andprimarily the top surface as the bottom of the dough piece is fully or partly shielded by theoven band. Answer: Convection is a mode of transferring heat. Listed below are 10 common examples of convection in everyday life. The Earth's surface receives unequal heating from the Sun. Goodemitters are also good absorbers of thermal radiation. They covera spectrum from gamma rays (around 10-14 metres) to radio waves (around 102 metres). Compared to it, its more direct: instead of inducing vibrations in the electrons inside your cookware, it causes the water molecules in the food to vibrate. Sauteing uses conduction to transfer the heat from the hot pan to the food. For objects other than perfect black bodies, the power ofradiation P is also proportional to the objects emissivity e. This relationship is described bythe Stephan-Boltzmann Law: where sigma = 5.67 x 10-8W / m2K4 and T is the temperature in Kelvin, Since the radiation is proportional to the temperature to the power of 4, a small increasein temperature will produce a very large increase in thermal radiation. This is especially important when Im about to bake loaves of bread and pizza pies on a baking stone. Moreover, the expansion of a material due to heating depends on thermal conductivity.
