Heat Transfer

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

• Conduction
• Radiation
• Convection
• Density
