Heat Transfer
- Infared radiation
- All objects emit and absorb infared radiation
- The hotter something is, the more IR it emits
- Dark,matt surfaces are good
absorbers and emitters of IR
- Light,shiny surfaces are poor
absorbers and emitters of IR,
but reflect it well
- All objects emit and absorb infared radiation
- Conduction and Convection
- Conduction
- CONDUCTION OF HEAT
IS WHEN VIBRATING
PARTICLES PASS ON KE
TO OTHER ONES.
- Occurs mainly in solids
- Works best in metals because of 'free electrons'
- Free electrons can move in the
metals and they pass the KE
around the metal onto other
particles very quickly.

- LESS DENSE HOT
PARTICLES RISE UP
FORCING COLD ONES

- Conduction
- Evaporation and Condensation
- Evaporation is when a
liquid turns into a gas
- Evaporation happens faster when
TEMPERATURE IS HIGHER,
DENSITY IS LOWER
SURFACE AREA IS LARGER.

turns into a gas
- Condensation is faster when
