RADIANT HEAT

  • Is the transfer of heat energy by invisible waves.
  • All objects give out heat radiation- the hotter an object is, the more heat it radiates.
  • An example of radiation is the Sun.

CONDUCTION HEAT

  • Occurs when heat is transferred from one object to another.
  • Metals are good conductors, therefore they are most likely to heat up when placed next to a warmer object.
  • Plastics are poor conductors (called 'insulators'), therefore they are more likely to remain the same temperature when placed next to a warmer object.
    An example of conduction is a hot cup of coffee on table- the table warms up.
