Across
- 5. the temperature at which it changes from a liquid to a solid
- 7. a measure of the average kinetic energy of the particles in an object or substance
- 10. has neither a definite shape nor a definite volume
- 11. discovered that when the temperature of a gas at constant pressure is decreased,its volume decreases
- 12. has a definite volume but no shape of its own
- 13. occurs when the surface particles of a solid gain enough energy that they form a gas
- 17. the temperature at which a liquid boils
- 18. the total kinetic and potential energy of all the particles in an object or substance
- 19. vaporization that takes place only on the surface of a liquid
Down
- 1. in place,meaning they move back and forth slightly
- 2. the change in state from a liquid to a gas
- 3. to make it wait
- 4. an inward force,or pull,among the molecules in a liquid that brings the molecules on the surface closer together
- 6. in a gas is the force of its outward push
- 8. resistance to flowing
- 9. occurs at a specific temperature
- 14. a definite shape and a definite volume
- 15. relationship between the pressure and the volume of a gas
- 16. the change in state from a gas to liquid
