Thermal Energy Transfer

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

Conduction is the transfer of heat through direct contact between materials.

Front

Give an example of conduction.

Back

Cooking eggs in a frying pan.

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

The warming of air inside a greenhouse.

Front

Define radiation.

Back

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

Front

Give an example of radiation.

Back

The melting of a snowman on a sunny day.

Front

What happens to air in a hot air balloon?

Back

The air inside the balloon heats up, becomes less dense, and causes the balloon to rise.

Front

What is the role of density in convection?

Back

Less dense (hotter) fluids rise while denser (cooler) fluids sink, creating a convection current.
