Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of thermal energy by collisions between particles.

Front

What is convection?

Back

Convection is the transfer of thermal energy in a fluid (liquid/gas) by movement of warm/cool fluids.

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves, such as heat from the sun.

Front

How does heat transfer through conduction occur?

Back

Heat transfer through conduction occurs when two objects are in direct contact and heat moves from the hotter object to the cooler one.

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 a campfire without touching it.

Front

What happens to particles during conduction?

Back

During conduction, particles collide and transfer energy to neighboring particles.

Front

What happens to fluids during convection?

Back

In convection, warmer fluids become less dense and rise, while cooler fluids become denser and sink.

Front

What is the role of density in convection?

Back

Density differences in fluids drive convection currents, causing warm fluids to rise and cool fluids to sink.
