  1. 2. a mixture in which the parts are noticeably different from one another.
  2. 3. any characteristic of a material that can be observed or measured without changing the composition of the substances in the material
  3. 6. a process that separates the substances in a solution based on their boiling points.
  4. 11. any ability to produce a change in the composition of matter.
  5. 15. the ability to be hammered without shattering
  6. 17. a process that separates materials based on the size of their particles.
  7. 18. a substance that is made from two or more simpler substances and can be broken down into those simpler substances.
  8. 19. the resistance of a liquid to flow
  9. 20. matter that always has exactly the same composition. (made of same substance)
  10. 21. a mixture in which the substances are so evenly distributed that it is difficult to distinguish one substance in the mixture from another.

  1. 1. The temperature at which a substance changes from solid to liquid (melts)
  2. 4. when one substance (solute) is dissolved into another substance (solvent) to form a homogenous mixture.
  3. 5. a material’s ability to burn in the presence of oxygen.
  4. 7. how readily a substance combines chemically with other substances
  5. 8. occurs when a substance reacts and forms one or more new substances.
  6. 9. occurs when some of the properties of a material change, but the substances in the material remain the same.
  7. 10. The temperature at which a substance changes from liquid to gas (boils)
  8. 12. contains some particles that are intermediate in size between the small particles in a solution and the larger particles in a suspension.
  9. 13. a substance that cannot be broken down into simpler substances. (C,H,O)
  10. 14. the ability of a material to allow heat or electricity to flow
  11. 16. a heterogeneous mixture that separates into layers over time.
