1. Conductors and Insulators of Heat

2. Conductor: An object that allows heat energy to flow freely through it. Examples: aluminum foil copper wire steel glass silverware

4. When do people use conductors of heat? Cook Food Boil water Can you think of more uses???

5. Insulator: An object that does not allow heat energy to flow freely through it. Examples: plastic wood rubber cloth paper

11. Melting point: The temperature point at which a solid turns into a liquid. Melting occurs at 0° Celsius.

12. Called Freezing Point if Decreasing Heat Called Melting Point if Increasing Heat
