dfg Conduction • Method of heat transfer by collision of molecules in a solid MUST BE TOUCHING!!!
dfg Convection • Transfer of heat through liquids and gases by means of currents Hot particles move faster and become less dense, so they move upwards, leaving cooler, slower moving particles at the bottom.
dfg Radiation • Process by which heat energy is transmitted through space
dfg Guess Which Method!!! CONDUCTION
