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