Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warm fluid rises and cool fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight, which can travel through a vacuum.

How does warm air behave in a room?

Back

Warm air rises because it is less dense than cooler air.

Front

What happens to cold air in a room?

Back

Cold air sinks because it is denser than warm air.

Front

What is an example of conduction?

Back

Touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection?

Back

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

Front

What is an example of radiation?

Back

Feeling the warmth of the sun on your skin.

Front

What is the role of insulation?

Back

Insulation reduces heat transfer between objects, keeping heat in or out.

Front

How does convection affect weather patterns?

Back

Convection currents in the atmosphere can lead to wind and weather changes.
