Conductors and Insulators of Heat

Conductor:

An object that allows heat energy to flow freely through it.

Examples: •aluminum foil•copper wire•steel• glass• silverware

When do people use conductors of heat?

Cook Food

Boil water

Can you think of more uses???

Insulator:

Boiling point:

The temperature point at which a liquid turns into a gas. Boiling occurs at 100° Celsius.

Freezing point:

The temperature point at which a liquid turns into a solid. Freezing occurs at 0° Celsius.

Melting point:

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

Called Freezing Point if Decreasing HeatCalled Melting Point if Increasing Heat

Remember…*Freezing goes from a liquid to a solid

*Melting goes from a solid to a liquid
