Front

What is a conductor?

Back

An object that transfers heat well.

Front

What is an insulator?

Back

An object that transfers heat poorly.

Front

What happens when you stir a boiling pot with a metal spoon?

Back

Heat would travel from the boiling pot to your hand.

Front

What happens when you put frozen ice cream into a metal bowl?

Front

What is the primary function of a conductor?

Back

To allow heat to flow easily.

Front

What is the primary function of an insulator?

Back

To prevent heat from flowing easily.

Front

How does temperature affect the conductivity of materials?

Back

Generally, as temperature increases, conductivity increases for conductors and decreases for insulators.
