Thermal Energy Transfer

Front

What is thermal energy transfer?

Back

The movement of energy from one object or substance to another due to a temperature difference.

Front

What is conduction?

Back

The transfer of heat through a solid material without the movement of the material itself.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

The transfer of energy through electromagnetic waves, which can occur in a vacuum.

Front

What happens to particles in a solid when heated?

Back

They vibrate faster and may move apart slightly, causing the solid to expand.

Front

What happens to particles in a gas when cooled?

Back

They slow down and come closer together, which can lead to condensation.

Front

What is an example of conduction?

Back

A metal spoon getting hot when placed in a pot of boiling water.

Front

What is an example of convection?

Back

Warm air rising and cool air sinking in a room, creating a circulation of air.

Front

What is an example of radiation?

Back

Feeling the warmth of the sun on your skin, even when standing in the shade.

Front

How does temperature affect particle movement?

Back

As temperature increases, particles move faster; as temperature decreases, particles move slower.
