Across
  1. 4. anything that has mass and takes up space.
  2. 7. ___Change - occurs when the internal make-up of the matter stays the same, even after the change, only shape, size and state are altered.
  3. 9. ___Substance - matter with both definite and constant composition and distinct chemical properties.
  4. 11. heterogeneous mixture in which consist of coarse particles which are visible to the naked eye.
  5. 12. state of matter that has a definite shape and volume.
  6. 15. the base unit used for volume.
  7. 16. method for separating mixtures that removes a liquid from a solution to leave a solid material.
  8. 17. ___Effect - the scattering of light as a light beam passes through a colloid.
  9. 18. the liquid that passes through the strainer.
  10. 19. chemical property of matter on whether the substance undergoes combustion or not .
  11. 21. defined as the substance that is dissolved in a solution.
  12. 22. process of allowing a mixture of solid and liquid or two immiscible liquids to settle and separate by gravity. Once the mixture components have separated, the lighter liquid is poured off, leaving the heavier liquid or solid behind.
  13. 23. the base unit used for length .
  14. 27. state of matter that has no definite shape or volume.
  15. 28. ___Property - the other term for intensive physical property.
  16. 32. sedimentation of particles under the influence of the centrifugal force and it is used for separation of superfine suspensions.
  17. 36. method for separating mixtures that involves solvent separation on a solid medium.
  18. 37. ___Property - the ability of a substance to react with other substances .
  19. 39. the process by which a substance changes from the solid phase to the liquid phase.
  20. 41. chemical property of matter on whether it will break into charged particles when in solution with water or not .
  21. 43. chemical property of matter on whether the substance can be easily decomposed or not.
  22. 44. the substance which remains in the strainer.
  23. 45. ___Chemistry - the study of the chemistry of matter and the development of tools to measure properties of matter.
  24. 46. is a chemical property of matter on whether the substance can damage an organism or not .
  25. 47. ___Change - occurs when a substance converted to a new substance.
  26. 48. ___Chemistry - the study of carbon and its compounds; the study of the chemistry of life.
Down
  1. 1. ___Property - can be measured and observed without changing the composition of the substance.
  2. 2. the simplest substances and hence cannot be broken down using chemical reactions.
  3. 3. ___Separation - process of separating elemental metals from other particles in a mixture .
  4. 5. dissolving medium .
  5. 6. method for separating mixtures that takes advantage of differences in boiling points.

  8. 11. substance changes from a solid to a gas without passing through a liquid phase.
  9. 13. method of separating mixtures using wind.
  10. 14. type of mixture in which the dispersed particles do not settle out.
  11. 20. method for separating mixtures that separates solids of different sizes.
  12. 24. chemical property of matter on whether it reacts with acids bases, and oxygen, gas or not.
  13. 25. the study of chemical processes that occur inside of living organisms.
  14. 26. physical combination of two or more substances .
  15. 29. branch of science that involves the study of the composition, structure and properties of matter.
