Ways Heat Transfers

What is the definition of CONDUCTION?

Hint: This transfer involves direct contact.

• 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.

What is the definition of RADIATION?

Hint: The sun is an example of this!

• 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.

Hint: Warm air rises while cooler air sinks.

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

• The transfer of heat through fluids (liquids and gasses).

• When heat transfers from objects that are touching.
