When a hot object touches a cooler object, heat energy is transferred from the warmer object to the cooler object through:

• radiation

• electrical energy

• conduction

• solar heating

You and your family are sitting around a campfire.  You can feel the heat on your face, even when you back your seat away from the fire.  The heat energy from the fire warms your face through:

• light energy from the fire

• conduction

• chemical reactions in the fire

• radiation

Choose the best example that represents heat transfer through convection.

• burning yourself on a hot iron

• lighting a bulb using a battery and wires

• getting a sun tan

• inflating a hot air balloon
