Forced convection is a process in which gasses or fluids are deliberately put in motion. This may be convection induced by a power source such as an air conditioner, pumps, fans, boilers, using your oven or boiling a pot of water.
Water boiling in a pan is a good example of these convection currents. Another good example of convection is in the atmosphere. The earth's surface is warmed by the sun, the warm air rises and cool air moves in.RADIATION--Radiation is a method of heat transfer that does not rely upon ...
Thermal energy can be transferred through three methods: conduction, convection and radiation. To best understand how each works, consider a pot of boiling water on a stove. Conduction is the flow of energy through solid materials. As the flame heats the pot, energy travels throughout the objec...
In a boiling water reactor the water passes through fuel channels to produce steam which gives up heat to a heat-exchanger within the pressure vessel, and the condensate returns down the outsides of the fuel channels, being heated by conduction through the walls of the channels so that it ...
SOUS VIDE- Insous vide cookingfood is vacuum sealed in a plastic bag and then cooked in water that is a specific temperature. Heat is transferred from the water to food via conduction. Sous vide devices that have the ability to circulate the water (convection) are more effective. ...

Gas and electric cooktops rely on a combination of convection and conduction, whereas a halogen cooktop uses the radiation from a halogen bulb under a ceramic glass surface to heat food. These powerful bulbs are filled with a halogen gas like bromine or iodine to create radiant heat, which he...

2. The amount of energy given off by the surface of the earth is claimed to be 79% radiation and 21% conduction and vaporization of water, as indicated by the Kiehl-Trenberth model published in the documents of the IPCC. Only white hot metals give off that much radiation in an air env...
