Convection Review

Front

What is convection?

Back

Convection is the process of heat transfer through the movement of fluids (liquids and gases) where warmer areas of a liquid or gas rise and cooler areas sink.

In which states of matter does convection occur?

Back

Convection occurs only in fluids, which include liquids and gases.

What is the difference between conduction, convection, and radiation?

Back

Conduction is heat transfer through direct contact, convection is heat transfer through fluid movement, and radiation is heat transfer through electromagnetic waves.

What is the role of density in convection?

Back

Density differences cause warmer, less dense fluids to rise and cooler, denser fluids to sink.

Front

How does convection affect weather patterns?

Back

Convection currents in the atmosphere can lead to the formation of clouds and storms.
