- 9. A tiny piece of matter (like an atom or molecule).
- 11. A rapid back-and-forth motion of particles.
- 16. Anything that has mass and takes up space.
- 20. When energy (like light or heat) is taken in by a material rather than reflected.

- 27. A transition from one state of matter to another
Down
- 1. When a gas loses energy and turns into a liquid.
- 2. State of matter that expands to fill its container.
- 3. This state of matter flows but has a constant volume.
- 5. Chemically inactive; does not react with other substances.
- 6. The gaseous state of a substance that is normally a liquid or solid at room temperature.
- 7. The movement of particles, which increases as energy is added.
- 10. The movement of energy from one object or system to another.
- 12. The smallest unit of an element that keeps its properties.
- 13. The transfer of heat through direct contact between particles.
- 14. When particles at the surface of a liquid gain enough energy to become a gas.
