Thermal Energy Transfer

Front

What is thermal energy transfer?

Back

The process of heat moving from one object or substance to another due to a temperature difference.

Front

What are the three main types of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

Define conduction.

Back

Conduction is 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

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

Front

Give an example of convection.

Back

Heat transfer in boiling water.

Front

Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light.

Front

Give an example of radiation.

Back

The sun warming your skin.

Front

What happens to warm air in convection?

Back

Warm air rises and cool air sinks.

Front

How does conduction occur in solids?

Back

Heat is transferred through the vibration and collision of particles in a solid.
