What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

What is radiation?

Back

The transfer of heat energy through electromagnetic waves without the need for a medium.

What happens to particles during convection?

Back

Warmer, less dense fluid rises while cooler, denser fluid sinks.
