Question

what is convection...​

Answer 1

Answer:

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 motion of matter.
• It happens in liquids and gases.
• It may be natural or forced.
• It involves a bulk transfer of portions of the fluid.
