Conduction, Convection, and Radiation

The heat from a lamp allows a lizard to remain warm. This is an example of which type of heat transfer?

• radiation
• conduction
• convection
• insulation

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.

What is the definition of CONVECTION

• When heat transfers through waves.
• 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.
• Heat traveling from the sun
