  1. 2. A principle that describes the relationship between pressure and volume of a gas at constant temperature
  2. 6. A liquid´s resistance to flowing
  3. 9. The temp. at which a substance changes from a solid to a liquid the same as the freezing point or temp. at which a liquid changes to a solid
  4. 10. The force pushing on the surface divided by the area of that surface
  5. 11. How hot or cold something is a measure of the average energy of motion of the average kinetic energy of the particles of a substance
  6. 13. The change in state from solid directly to a gas without passing through the liquid state
  7. 14. A state of matter with no definite or volume
  8. 16. The change of state from liquid to a gas
  9. 17. The result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together causes the surface to act as if it has a thin skin
Down
  1. 1. The temperature at which liquid boils
  2. 3. A state of matter that has a definite shape and a definite volume
  3. 4. The change in state from a gas to a liquid
  4. 5. A state of matter that has no definite shape but has a definite volume
  5. 7. Energy The total kinetic and potential energy of all the particles of an object
  6. 8. A principle that describes the relation between the temp. and volume of a gas at constant pressure
  7. 12. The process by which molecules at the surface of a liquid absorb enough energy to change into a gas
  8. 15. The temp. at which a liquid freezes
