convection (redirected from convections)

con·vec·tion  (kn-vkshn) 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 convecti, convectin-, from convectus, past participle of convehere, to carry together : Latin com-, com- + Latin vehere, to carry; see wegh- in Indo-European roots.] con·vection·al adj. con·vective adj. con·vective·ly adv.

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.

Noun

the transmission of heat caused by movement of molecules from cool regions to warmer regions of lower density [Latin convehere to bring together]

convection  (kn-vkshn)

Current in a fluid caused by uneven distribution of heat. For example, air on a part of the Earth's surface warmed by strong sunlight will be heated by contact with the ground and will expand and flow upward, creating a region of low pressure below it; cooler surrounding air will then flow in to this low pressure region. The air thus circulates by convection, creating winds. See Note at conduction.
