Conduction, Convection, Radiation

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat by the movement of fluids (liquids or gases) where warm fluid rises and cool fluid sinks.

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves through empty space.

Front

Give an example of conduction.

Back

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

Front

Give an example of convection.

Back

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

Front

Give an example of radiation.

Back

Feeling the warmth of the sun on your skin.

Front

What happens to warm air in a room?

Back

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

Front

What is the main difference between conduction and convection?

Back

Conduction requires direct contact, while convection involves the movement of fluids.

Front

What is an example of heat transfer in a liquid?

Back

When you heat soup on the stove, the hot soup rises and cooler soup moves down.

Front

What is the role of density in convection?

Back

Warm fluids are less dense and rise, while cooler fluids are denser and sink.
