... the result of air's lower density at elevated temperatures and its affinity to rise. Cooler air sinks due to the increase in density. 4, record 2, English, - natural%20convection
Record number: 2, Textual support number: 1 OBS
Convection. Process of heat [(transfer of heat)] carried from one point to another by movement of a liquid or a gas (i.e., air). Natural convection is caused by expansion of the liquid or gas when heated. Expansion reduces the density of the medium, causing it to rise above the cooler, more dense portions of the medium. Gravity heating systems are examples of the profitable use of natural convection. The air, heated by the furnace, becomes less dense (consequently lighter) and rises, distributing heat to the various areas of the house without any type of blower. When a blower is used, the heat transfer method is called "forced convection." 5, record 2, English, - natural%20convection

The term convector refers to a heat-distributing unit that operates with gravity-circulated air and has a heating element with a large amount of secondary surface containing two or more tubes headered at both ends. The heating element is surrounded on all sides by an enclosure having an air inlet opening below, and an air outlet opening above the heating element. 3, record 3, English, - convector
