24 Lets heat through Conductor
This is the key fact about a conductor. If one part gets hot, the heat spreads to the rest of it too.

25 Does not let the heat through
Insulator An insulator is the opposite of a conductor. So it does not let heat through.

26 Metals are good conductors.

27 Base of a saucepan Conductor
The heat must get through the bottom of the saucepan into the food. So the base must be a conductor.

28 Plastics do not let heat through them. They are insulators.

29 Table mat Insulator The job of a table mat is to stop heat getting from a hot plate or mug onto the table. It must be an insulator.

30 Saucepan handle Insulator
The handle must stay cool even when the saucepan is hot. So it must be an insulator so heat does not pass along it.

31 Radiator Conductor A radiator is full of hot water (or hot oil). The heat from this must pass through the radiator into the room.

32 Cold tile floor (ie which feels cold with bare feet)
Conductor This is a tricky example! Your feet are at body temperature – ie warmer than the floor. The tiles conduct this heat away so they still feel cold.

33 Suitable as a layer in your loft
Insulator The padding you put in your loft is there to stop heat escaping from the house. It must be an insulator.
