What Is Convection? - Heat Definition, Types of Convection, Examples ...
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 is the process of heat transfer in fluids by the actual ...

10 Common Examples Of Convection (with Pictures) - Afrilcate
8. Refrigerator. Another common example of convection heat transfer is the household refrigerator. The process by which a refrigerator removes heat from the refrigeration compartments relies on the concept of convection. In refrigerators, convection occurs through the use of refrigerant gases and compressor.

Convection (heat transfer) - Wikipedia
A hot, less-dense material at the bottom moves upwards, and likewise, cold material from the top moves downwards. Convection (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 ...
