							some examples

CONDUCTION:

  • Touching a stove and being burned
  • Ice cooling down your hand
  • Boiling water by thrusting a red-hot piece of iron into it

CONVECTION:

  • Hot air rising, cooling, and falling (convection currents)
  • An old-fashioned radiator (creates a convection cell in a room by emitting warm air at the top and drawing in cool air at the bottom).

RADIATION:

  • Heat from the sun warming your face
  • Heat from a lightbulb
  • Heat from a fire
  • Heat from anything else which is warmer than its surroundings.
