Front

What happens to the particles in a solid when heated?

Back

They gain energy and may begin to vibrate more, potentially changing to a liquid.

Front

What happens to the particles in a liquid when heated?

Back

They gain energy and may move faster, potentially changing to a gas.

Front

What happens to the particles in a gas when cooled?

Back

They lose energy and may come closer together, potentially changing to a liquid.

Front

What is the particle theory of matter?

Back

It states that all matter is made up of tiny particles that are in constant motion.
