Most pots and pans are metal or glass because...

• These materials are conductors that speed up heat transfer.

• These materials expand and contract a lot when heated and cooled.

• These materials are insulators that slow down heat transfer.

• These materials have very low mass so they can hold a lot of thermal energy.

Why does a bathtub of hot water stay warmer longer than a cup of hot water?

• The cup loses thermal energy while the bathtub does not.

• The bathtub has more mass, so it also has more thermal energy.

• The cup of water has a lower boiling point.

• The bathtub is an insulator, while the cup is a conductor.
