Conduction, Convection and 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) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

Front

Give an example of conduction.

Back

Touching a hot iron is an example of conduction.

Front

Give an example of convection.

Back

Boiling water in a pot is an example of convection.

Front

Give an example of radiation.

Back

The sun warming your face is an example of radiation.

Front

What happens to warm air in a room?

Back

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

Front

What is the primary method of heat transfer in liquids?

Back

Convection is the primary method of heat transfer in liquids.

Front

How does heat travel from the sun to the earth?

Back

Heat travels from the sun to the earth through radiation.

Front

What is the role of density in convection?

Back

In convection, warmer, less dense fluid rises while cooler, denser fluid sinks, creating a circulation pattern.
