What happens to particles in a solid when energy is added?

Back

The particles vibrate faster and may eventually break free from their fixed positions.

Front

What is a phase change?

Back

A phase change is a transition of matter from one state to another, such as solid to liquid or liquid to gas.

Front

What occurs during melting?

Back

During melting, a solid absorbs energy and its particles move apart to form a liquid.

Front

What occurs during freezing?

Back

During freezing, a liquid loses energy and its particles come together to form a solid.

Front

What is the relationship between temperature and energy?

Back

As temperature increases, the energy of the particles in a substance also increases.
