  • Energy transfer by heating
    • Infrared rediation
      • Things emit infrared
      • the hotter an object is, the more infrared radiation it emits in a given times
    • Surfaces and radiation
      • Dark, matt surfaces are better at emitting radiation than light shiny surfaces
      • Light, shiny surfaces absorb less radiation than dark matt surfaces
      • Light, shiny surfaces reflect more radiation than Dark,matt surfaces
    • Conduction
      • Metals conduct energy better than non-metals
      • Copper is a better conductor than steel
      • Wood conducts better than gas
    • Convection
      • Only occurs in fluids
      • Hot fluids rise, cool fluids drop
