Heat Energy Quiz

Heat travelling through solid metals is a form of

Heat travelling from the Sun to the Earth does so through

Hot air rising and cool air falling is an example of ......... currents

The reason why handles of metal pots are made of plastic is because

• plastic is a conductor

• plastic is an insulator

• it won't melt as it is too far from the hot plate

• it's too dangerous to make handles out of wood

The reason why electric wires are covered with plastic coating is

• it prevents you from adding heat to the wires

• it insulates the holder from electric currents

• it keeps the heat in so that the wires don't get cold

• it helps with the electricity to run down the wire more quickly

Match the following

• conduction

• 
• radiation

• 
• convection

•
