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 thermal energy transfer?

Back

Conduction, convection, and radiation.

Front

Define conduction.

Back

The transfer of heat through direct contact between materials.

Front

Define convection.

Back

The transfer of heat through the movement of fluids (liquids or gases) due to differences in temperature.

Front

Define radiation.

Back

The transfer of heat in the form of electromagnetic waves, which can occur through space.

Front

How does heat transfer occur in conduction?

Back

Heat is transferred when two objects at different temperatures touch each other.

Front

Give an example of conduction.

Back

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

Front

How does heat transfer occur in convection?

Back

Warm air or liquid rises, while cooler air or liquid sinks, creating a circulation pattern.

Front

Give an example of convection.

Back

Boiling water where hot water rises to the top and cooler water sinks.

Front

How does heat transfer occur in radiation?

Back

Heat is transferred without direct contact, through electromagnetic waves.
