Front

What is a conductor?

Back

A material that allows heat to pass through it easily.

Front

How does heat move in conduction?

Back

Heat moves from particles with higher temperature to particles with lower temperature.

Front

What happens to particles in a substance when it is heated?

Back

The particles gain energy and move faster.

Front

What is the role of currents in convection?

Back

Currents help distribute heat throughout a liquid or gas.
