Presentation transcript:

Conduction The transfer of energy as heat between particles collide within a substance or between two objects in contact Two objects of unequal temperature in contact

Convection The transfer of energy by the movement of fluids (liquid or gas) with different temperatures Convection currents- cycle of heated fluid rising and then cooling and falling

Radiation The transfer of energy by electromagnetic waves (infrared radiation, visible light, ultraviolet rays) Does not involve the movement of matter Only method of energy transfer that can occur in a vacuum (outer space)
