Heat Transfer

What is the definition of CONDUCTION?

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

• A hot liquid or gas 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 gas that expands, becomes less dense, and rises or becomes more dense, and sinks.

• Heat traveling from the sun

This is a lava lamp. When the light bulb heats the wax, the wax rises. When the wax cools, it falls. This cycle of rising/falling is an example of:

• Conduction.
• Convection.
• Radiation.
• Liquid

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

• Conduction
• Convection
• Radiation
• Insolation 

The baby chickens are kept warm from the heat lamps demonstrates this type of heat transfer. 

• Conduction
