Thermal Energy Transfer

Front

What is thermal energy transfer?

Back

The movement of heat from one object or substance to another.

Front

What are the three main types of thermal energy transfer?

Back

Conduction, Convection, and Radiation.

Front

Define conduction.

Back

The transfer of heat through direct contact between materials.

Front

Give an example of conduction.

Back

Placing a metal spoon in a hot pot of soup.

Front

Define convection.

Back

The transfer of heat through the movement of fluids (liquids and gases).

Front

Give an example of convection.

Back

Boiling water where hot water rises and cooler water sinks.

Front

Define radiation.

Back

The transfer of heat in the form of electromagnetic waves, such as light.

Front

Give an example of radiation.

Back

Feeling warmth from the sun on your skin.

Front

What happens to particles during conduction?

Back

Particles collide and transfer energy to neighboring particles.

Front

What happens to particles during convection?

Back

Warmer, less dense particles rise while cooler, denser particles sink.
