Explain how thermal energy is transferred in convection.

Convection is the transfer of heat energy in a fluid. This type of heating is most commonly seen in the kitchen with a boiling liquid. Air in the atmosphere acts as a fluid. ... As the hot air mass rises, the air is replaced by the surrounding cooler, more dense air, what we feel as wind.

Everyday Examples of Convection

Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion. ... Steaming cup of hot tea - The steam is showing heat being transfered into the air.
