  1. 1. a type of chemical reaction that absorbs energy to break bonds, getting colder in the process
  2. 6. a characteristic of matter related to the current state of matter
  3. 9. when two more substances cause a chemical change to occur
  4. 12. a law that states that matter can never be created or destroyed; only changed
  5. 13. a change in matter that DOES change the chemical composition of matter; physical properties are usually changed too
  6. 14. the resistance a fluid has to flowing

  1. 2. a type of chemical reaction that releases stored energy when bonds are created, getting hotter in the process
  2. 3. a measurement of the average amount of kinetic energy in a substance
  3. 4. a change in matter does NOT change the chemical composition of matter; only physical properties are changed
  4. 5. a theory that explains what happens to matter when the amount of energy is increased or decreased
  5. 7. the amount of space matter takes up
  6. 8. a characteristic of matter that is related to its ability to change its chemical composition
  7. 10. a measurement of how compact the molecules in matter are
  8. 11. the constant pushing force exerted by one thing on another
