Front

What is convection?

Back

Convection is the transfer of heat through currents in fluids (liquids and gases).

Front

What is an example of convection?

Back

Water molecules in boiling water moving in currents.

Front

In which direction does heat transfer occur?

Back

Heat transfer always occurs from hot to cold.

Front

What is the difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection occurs through fluid movement.
