Physics Unit 1 Revision

1. Energy Transfer

   • Infrared Radiation
     • All objects take in and emit infrared radiation.
     • Hotter objects emit more infrared radiation. Dark surfaces are good absorbers and good emitters while shiny surafces are poor. Shiny surfaces are good reflectors of radiation.
   • Kinetic Theory
     • Kinetic theory states that when a substance transfers from solid to liquid to gas, it becomes more energized.
   • Energy Transfer By Heating
   • Heating and Insulating Buildings

2. Energy and Efficiency
