Convection | Definition, Examples, Types, & Facts | Britannica
https://www.britannica.com/science/convection
WebConvection, process by which heat is transferred by movement of a heated fluid such as air or water. Natural convection results from the tendency of most fluids to expand when heated—i.e., to become less dense and to rise as a result of the increased buoyancy. Circulation caused by this effect.

Convection - Wikipedia
https://en.wikipedia.org/wiki/Convection
WebConvection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be …

CONVECTION Definition & Meaning | Dictionary.com
https://www.dictionary.com/browse/convection
WebConvection is the transfer of heat by the movement of heated parts of liquids and gases. Convection happens in liquids and gases because, unlike in a solid, molecules are able to freely move. For example, the air molecules in your living room continually move around, all moving at about the same speed.

Convection (heat transfer) - Wikipedia
https://en.wikipedia.org/wiki/Convection_(Heat_transfer)
WebConvection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of conduction (heat diffusion) and advection (heat transfer by bulk fluid flow ).

WebFeb 20, 2022 · Convection is driven by large-scale flow of matter. In the case of Earth, the atmospheric circulation is caused by the flow of hot air from the tropics to the poles, and the flow of cold air from the poles toward the tropics. (Note that Earth’s rotation causes the observed easterly flow of air in the northern hemisphere).

Convection – The Physics Hypertextbook
https://physics.info/convection/
WebConvection is the transfer of internal energy into or out of an object by the physical movement of a surrounding fluid that transfers the internal energy along with its mass. Although the heat is initially transferred between the object and the fluid by conduction, the bulk transfer of energy comes from the motion of the fluid.

Convection - Energy Education
https://energyeducation.ca/encyclopedia/Convection
WebConvection is a way for heat to move, also referred to as a heat transfer mechanism. This transfer of heat happens when a fluid such as air or water is in motion. Convection is driven by temperature differences across that fluid.
