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 hot fluid rises and cold fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation from the sun.

Front

Give an example of convection.

Back

When you are making soup and the water is rising and lowering.

Front

What happens to a hot liquid or air in convection?

Back

It expands, becomes less dense, and rises.

Front

What is the worst absorber of infrared radiation?

Back

A shiny white surface.

Front

How does heat transfer between areas of different temperatures?

Back

Heat transfers from an area of high temperature to an area of low temperature.

Front

What is the role of density in convection?

Back

In convection, hot fluids are less dense and rise, while cold fluids are more dense and sink.

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 radiation?

Back

Feeling the warmth of the sun on your skin.
