Convection | Definition, Examples, Types, & Facts | Britannica
WEBJul 11, 2024 · convection, 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 …
What Is Convection? - Heat Definition, Types of Convection, …
WEBConvection 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 …
Convection – The Physics Hypertextbook
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.

Thermal conduction, convection, and radiation - Khan Academy
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 - Energy Education
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.

Heat transfer | Definition & Facts | Britannica
WEBJul 19, 2024 · Heat transfer, any or all of several kinds of phenomena, considered as mechanisms, that convey energy and entropy from one location to another. The specific mechanisms are usually referred to as convection, thermal radiation, and conduction. Transfer of heat usually involves all these processes.
