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.

The baby chickens are kept warm from the heat lamps. This demonstrates what kind of heat transfer? 

• conduction
• convection
• radiation

The transfer of heat by currents through liquids of gases is called

• Perspiration
• Radiation
• Conduction
• Convection
