Answer 2

Explanation:

Convection is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, including molten rock ( rheid ). Convection includes sub-mechanisms of advection (directional bulk-flow transfer of heat), and diffusion (non-directional transfer of energy or mass particles along a concentration gradient).

Everyday Examples of Convection

Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. ...

Radiator - Puts warm air out at the top and draws in cooler air at the bottom.

Steaming cup of hot tea - The steam is showing heat being transfered into the air.
