Conducts heat or insulates
Words to learn: conductor • insulator • heat • transfer
A saucepan must let heat reach the food, but its handle should not become too hot to hold.
WHAT IS THE PROPERTY?
A thermal conductor lets heat move through it readily. A thermal insulator slows the movement of heat.
HOW CAN WE TEST IT?
Keep one end of equal samples warm and compare how quickly the other end changes temperature. Use safe classroom equipment.
WHY DOES IT MATTER?
Cooking pans need good heat transfer, while pan handles, oven gloves and house insulation need to slow heat transfer.
