Back

Radiation.

Front

____________________: the rising and falling of particles as they're heated (i.e. heat rises, cold falls).

Back

Convection.

Front

What is conduction?

Back

Heat transfer through direct contact between materials.

Front

What is convection?

Back

Heat transfer through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

Heat transfer through electromagnetic waves without the need for a medium.

Front

What happens to the density of air as it is heated?

Back

It becomes less dense and rises.

Front

What is the role of a conductor in heat transfer?

Back

A conductor allows heat to pass through it easily.
