What is conduction?

Back

Conduction is the transfer of heat from one object to another through direct contact.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) where warm fluid rises and cool fluid sinks.

How does cool air behave in convection?

Back

Cool air sinks because it is denser than warm air.

What happens to the density of a liquid when it is heated?

Back

When a liquid is heated, it expands, becomes less dense, and rises.
