Thermal Energy Transfers

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 thermal energy through direct contact between materials.

Front

Define convection.

Back

The transfer of thermal energy through the movement of fluids (liquids and gases) caused by density differences.

Front

Define radiation.

Back

The transfer of thermal energy through electromagnetic waves, such as light.

Front

What is an example of conduction?

Back

A metal spoon getting hot when placed in a hot soup.

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 warmth from the sun on your skin.

Front

What happens to thermal energy when two objects at different temperatures come into contact?

Back

Thermal energy transfers from the hotter object to the cooler object until they reach thermal equilibrium.

Front

What is thermal equilibrium?

Back

A state where two objects in contact have the same temperature and no net heat transfer occurs.
