• When heat is transferred from objects like rays of light or electromagnetically.

• When heat transfers from objects that are touching.

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

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