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 and 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

Which material is a good conductor of heat?

Back

Copper is a good conductor of heat.

Front

Which material is a good insulator?

Back

Wool is a good insulator.

Front

What happens to a car's inside temperature on a sunny day?

Back

A car’s inside temperature rises to over 100 degrees due to radiation.

Front

How does heat travel through liquids and gases?

Back

Heat travels through liquids and gases primarily by convection.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot soup.

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 warmth from the sun on your skin.
