Types of Heat Transfer

Front

What is convection?

Back

Convection is the transfer of heat through a hot liquid or air that expands, becomes less dense, and rises, or becomes more dense and sinks.

What is the circular movement of heated liquids or gases due to density differences called?

Back

Convection current.

Front

How does heat move?

Back

Heat moves from a warmer object to a cooler object.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat to pass through easily.
