Conduction, Convection & Radiation

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the flow of liquids and gases.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, without the need for a medium.

Front

How does thermal energy move?

Back

Thermal energy moves in a predictable pattern, from warmer sites to cooler sites.

Front

What is an example of conduction?

Back

An example of conduction is touching a hot stove and feeling the heat.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

What happens to particles during conduction?

Back

In conduction, particles vibrate and transfer energy to neighboring particles.

Front

What happens to particles during convection?

Back

In convection, warmer particles move up while cooler particles move down, creating a flow.

Front

What is the role of a medium in conduction?

Back

In conduction, a medium (solid, liquid, or gas) is necessary for thermal energy transfer.
