2. A state of matter in which the particles vibrate in fixed positions close to each other
4. To be squashed to take up less space
6. A set of statements that explains the behaviour of particles in solids, liquids and gases is called the ..... theory of matter

16. The amount of space something occupies

1. Decreasing in size due to decreased particle vibrations and space occupied by particles
3. Change state from a solid to a liquid
5. The amount of matter that makes up a substance
7. To change state from a gas to a liquid
9. Increasing in size due to increased particle vibrations and the space occupied by particles
13. Anything that takes up space and has mass
15. A state of matter in which the particles are close together but move freely past one another
