Convection
· Convection - The transfer of thermal energy by moving particles in fluids
· As the particles of fluids (gases and liquids) are heated, they move faster and expand; this expansion makes the fluids less dense so they rise
· When warmer fluids rise, cooler fluids move downwards; this creates a “convection current”
· The convection current continues in a pot of soup because the warmer soup particles in a pot cool when they make contact with the air and then sink. These particles are heated again once they meet the bottom of the pot.
· Convection currents help heat your home through your furnace heating system.
