CONDUCTION, CONVECTION, RADIATION

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.

Warm air rises and the cool air sinks demonstrates this type of heat transfer.
