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 methods 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).

Front

Define radiation.

Back

The transfer of heat through electromagnetic waves without the need for a medium.

Front

Give an example of conduction.

Back

A hot mug of cocoa warming the table it sits on.

Front

Give an example of convection.

Back

Boiling water in a pot where hot water rises and cool water sinks.

Front

Give an example of radiation.

Back

The sun warming your skin.

Front

How does heat transfer occur when roasting marshmallows?

Back

Heat from the fire is radiated to the marshmallow.

Front

What happens to the thermal energy of a hot object when it comes in contact with a cooler object?

Back

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