Across
- 4. The space that holds a gas and can change pressure or volume.
- 7. Rises because heated air inside is less dense.
- 8. Gas law: volume ↑ when temperature ↑ (at constant pressure).
- 9. How tightly packed gas particles are in a space
- 10. Gas law: pressure ↑ when temperature ↑ (at constant volume).
- 12. A measure of how fast gas particles move.
- 15. Expands in warmth, shrinks in cold due to gas behavior.
Down
- 1. What happens to a gas when it’s heated (takes up more space).
- 2. Squeezing a gas into a smaller volume.
- 3. Energy of motion of gas particles.
- 5. The force of gas particles colliding with container walls.
- 6. Gas law: pressure ↑ when volume ↓ (at constant temp).
- 11. Example of pressure ↑ when temperature ↑ at fixed volume.
- 13. Tiny bits of matter that make up gases, liquids, and solids
- 14. The amount of space a gas occupies.
