Across
- 3. the average kinetic energy of the particles of matter
- 4. The process in which a solid changes directly to a gas
- 5. The process in which a gas changes to a liquid
- 6. if the volume of a gas is held constant, increasing the temperature of the gas increases its pressure
- 8. if the pressure of a gas is held constant, increasing the temperature of the gas increases its volume
- 9. the ability to cause changes in matter
- 10. the amount of force pushing against a given area
- 12. matter that has neither a fixed volume or shape
- 15. if the temperature of a gas is held constant, increasing the volume of the gas decreases its pressure
- 16. The energy of moving matter
- 19. all matter consists of constantly moving particles
Down
- 1. The process in which a liquid boils and changes to a gas
- 2. the process in which a gas changes directly to a solid without going through the liquid state
- 7. the different forms in which matter can exist
- 10. state of matter that resembles a gas but has certain properties that a gas does not have.
- 11. when particles at the exposed surface of a liquid absorb just enough energy to pull away from the liquid and escape into the air
- 13. matter that has neither a fixed volume or shape
- 14. matter that has a fixed volume but not a shape
- 17. The process in which a solid changes to a liquid
- 18. The process in which a liquid changes to a solid
