Question

The transfer of heat energy by the circulation of warm air is called

Answer 1

Convection.

Step-by-step explanation:

It is defined as the transfer of heat which take place because of the bulk movement of molecules with in fluids. This kind of transfer of energy is generally seen in liquids and gases because in most of the solids there is no bulk current flow and significant diffusion of matter can also not take place.

Convectional heat transfer is one of the major type of heat transfer which have crucial role in the atmospheric circulation and in generation of localized weather phenomenon.

Answer 2

Convection

Step-by-step explanation:

The convection is the transfer of heat due to the kinetic energy (or movement) of molecules within fluids, such as liquids ans gases, and warm air is a gas.

There are also two type of convection, which both could be achieved by warm air, free convection and force convection.

Hope this helps!
