What is Conduction?

• When heat is passed from particle to particle through an object.

• When particles get heated, expand, and become less dense.

• When heat transfers by waves through empty space.

Sam placed a glass of water in the refrigerator. After about an hour he took it out and found it to be colder.

What is the most likely thing that happened?

• the cold that was in the refrigerator transferred into the water

• the particles in the water started to move faster

• the cold from the refrigerator radiated into the glass

• the heat that was in the water transferred out into the refrigerator
