Thermal Energy Transfer

Front

What is thermal energy transfer?

Back

The process of heat moving from one object or substance to another.

Front

What are the three main types of heat 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

Walking on hot sand with bare feet.

Front

Define convection.

Back

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

Front

Give an example of convection.

Back

Heat rising in a hot air balloon.

Front

Define radiation.

Back

The transfer of heat through electromagnetic waves without needing a medium.

Front

Give an example of radiation.

Back

Feeling warmth from the sun or a campfire.

Front

What happens to thermal energy when you place a hot mug on a table?

Back

Thermal energy is transferred from the mug to the table through conduction.

Front

How does heat transfer occur in a boiling pot of water?

Back

Through convection, as hot water rises and cooler water sinks.
