Heat Transfer Review

What is the definition of conduction?

• When heat is transferred by rays of light or electromagnetically.

• a hot liquid or air that expands, becomes less dense, and rises or cools to becomes more dense and sinks.

• When heat transfers between two objects that are touching.

• When heat transfers through the heater or air conditioner in your house.
