convection
Air heated by a space heater rises and is replaced by cool air, creating a convection current that circulates hot air throughout a room.

con·vec·tion

 (kən-vĕk′shən)
n.
1. The act or process of conveying; transmission.
2. Physics
a. Heat transfer in a gas or liquid by the circulation of currents from one region to another.
b. Fluid motion caused by an external force such as gravity.
3. Meteorology The transfer of heat or other atmospheric properties by massive motion within the atmosphere, especially by such motion directed upward.

[Late Latin convectiō, convectiōn-, from convectus, past participle of convehere, to carry together : Latin com-, com- + Latin vehere, to carry; see wegh- in Indo-European roots.]

convection

(kənˈvɛkʃən)
n
1. (General Physics) a process of heat transfer through a gas or liquid by bulk motion of hotter material into a cooler region. Compare conduction1
2. (Physical Geography) meteorol the process by which masses of relatively warm air are raised into the atmosphere, often cooling and forming clouds, with compensatory downward movements of cooler air
3. (Geological Science) geology the slow circulation of subcrustal material, thought to be the mechanism by which tectonic plates are moved
[C19: from Late Latin convectiō a bringing together, from Latin convehere to bring together, gather, from vehere to bear, carry]

con•vec•tion

(kənˈvɛk ʃən)

n.
1. the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.
2. the vertical transport of atmospheric properties, esp. upward (disting. from advection).
3. the act of conveying or transmitting.

convection
Air heated by a space heater rises, then cools and falls to be heated and rise again. This cycle creates a convection current that circulates hot air throughout a room.

con·vec·tion

(kən-vĕk′shən)
The transfer of heat energy through liquids and gases by the movement of molecules. When molecules of the liquid or gas come in contact with a source of heat, they move apart and away from the source of heat, and cooler molecules take their place. Eventually, as the cooler molecules are heated, they move as well, and a convection current forms, transferring the heat. See Note at conduction.

convection

the vertical movement of elements of the atmosphere. Cf. advection.

convection

1. The upward motion of a body of air which transfers heat from ground level to the upper part of the atmosphere.
2. Heat transfer by means of currents circulating through fluids.
