Heat and Energy

Think about a pan of water sitting on an electric stove. The stove is then turned on to high.

How is heat transferred from the stove to the pan?

• conduction

• convection

• radiation

• temperature

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
