Convection.
dont know
The movement of matter during convection is what transfers thermal energy.The air or liquid currents help transferring thermal energy through convection as the currents of higher temperature are of less density (lighter) and move upwards while that of less temperature are of higher density (heavier) and move downwards.Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids (liquids or gases). Convection is usually the dominant form of heat transfer in liquids and gases.
Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.
Both conduction and convection are types of heat transfer, meaning they move heat from one object to another. The difference is how they transfer the heat. Conduction transfers heat from touching solid to touching solid, while convection transfers heat in fluids (liquid or a gas).Convection transfers heat by having the warm types of fluid rise while the cold sinks. This creates something called a convection current.

Both conduction and convection require an intervening medium, but convection requires the medium to be able to move.

conduction's heat energy is sometimes transfered between two different objects. But convection's heat energy is transfered through the particles in a liquid or gas move.
