- 1. Anything that has mass and takes up space
- 5. When liquid reaches this, it has enough energy to become a gas
- 7. High-energy state made up of charged particles
- 8. The basic building blocks of all substances
- 11. Liquid to Solid- Remove heat to slow particles
- 12. Gas to Solid- Reverse of sublimation, such as frost forming on a cold surface

- 14. Particles move freely and spread out to fill the space available
- 15. Has a definite shape and volume
Down
- 2. Liqid to Gas- When particles escape to become a gas (think disappearing water)
- 3. Gas to Liquid- When water droplets form on a cold glass of lemonade on a hot day
- 4. Matter that takes the shape of its container but maintains volume
- 6. Solid to Liquid- Particles separate when heat is applied
