- Convection | Definition, Examples, Types, Facts | Britannica
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 and to rise as a result of the increased buoyancy
- Convection - Wikipedia
Convection is single or multiphase fluid flow that occurs spontaneously through 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 assumed
- Convection – Definition, Examples, Types - Science Notes and Projects
Convection is the process of heat transfer within a fluid due to the movement of the fluid itself When a part of the fluid becomes warmer, it typically becomes less dense and rises, while cooler, denser fluid sinks This creates a flow that redistributes heat
- What is Convection? - BYJUS
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: Definition and Examples - Science Facts
Convection is the heat transfer process from one region to another due to the movement of fluids like air or water The initial heat transfer occurs through conduction, but the primary transfer occurs through convection It is the dominant form of heat transfer in liquids and gases Types of Convection
- Convection: What Is It How Does It Work? - Sciencing
Convection is a method of thermal energy transfer where the transfer of heat occurs via fluid motion This fluid motion is caused by the difference in density between hotter regions of the fluid and cooler regions
- 14. 6: Convection - Physics LibreTexts
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
Convection 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
