- 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
- Infrared rediation
