Conduction is the movement of this energy 1 of 6 Good Conductors Metals as they have a free electrons. and are closely packed so vibrate a lot. 2 of 6 Convection Transfer of energy through liquids or gases. 3 of 6 Convection Currents Air warms up due to conduction, the sair expands and becomes less dense and rises, as the air cools it sinks 4 of 6 Radiation Radiation is the transfer of energy through Infrared Waves 5 of 6 Infrared waves Travel through a vacuum, Travel at the speed of light, Can be reflected and absorbed. 6 of 6
