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 …

WEBConduction involves molecules transferring kinetic energy to one another through collisions. Convection occurs when hot air rises, allowing cooler air to come in and be heated. Thermal radiation happens when accelerated charged particles release electromagnetic radiation, which can be felt as heat. Questions.

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 heat transfer by the macroscopic movement of mass. Convection can be natural or forced and generally transfers thermal energy faster than conduction. The table gives wind-chill factors, indicating that moving air has the same chilling effect of much colder stationary air.

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.

WEBWhat is Convection? Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid.

Convection - Energy Education
https://energyeducation.ca/encyclopedia/Convection
WEBConvection - Energy Education. Convection 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.
