Across
  1. 3. A process in which a conversion factor written in a form of ratio is used to change the units given in the data to the units desired
  2. 4. The digits in any measurement that are known with certainty with an additional one digit which is uncertain
  3. 6. Chemical property whether it reacts with acids, bases, gases or not
  4. 9. Solid particles are allowed to settle first, then the liquid is poured into another container leaving behind the solid particles
  5. 12. Also known as intrinsic physical property
  6. 13. Type of heterogeneous mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance.
  7. 14. The study of chemical processes that occur inside of living organisms
  8. 15. Any substance that has mass and takes up space by having volume
  9. 19. The ability/characteristic of a substance to react with other substances such as air, water, acid & base
  10. 20. The consistency of a result
  11. 21. Chemical property whether the substance can damage an organism or not
  12. 23. The phase transition in which liquid turns to gas
  13. 27. The phase transition in which gas turns to liquid
  14. 29. Composed of two or more substances combined physically in variable proportions
  15. 32. Also known as extrinsic physical property
  16. 34. Tells how hot or cold an object is
  17. 36. Chemical property whether the substance undergoes combustion or not
  18. 39. The simplest form of matter
  19. 40. Process of separating elemental metals from other particles in a mixture with the use of a magnet
  20. 42. is a system in which an ordinary decimal number is expressed as the product of a number between 1 and 10 times 10 raised to a power; expressed as N x 10n
  21. 43. Has indefinite shape and volume
  22. 44. Has definite shape and volume
  23. 45. The phase transition in which a substance changes from solid to gas without ever through the liquid state
  24. 47. It is the ratio of the mass of an object to the volume it occupies
  25. 48. Another method of separating complex mixtures; The mixture is dissolved in a fluid which carries it through a structure holding another material. The various constituents of the mixture travel at different speeds, causing them to separate.
  26. 49. Also called solution; Type of mixture in which the components are uniformly distributed throughout
Down
  1. 1. A process of separating solid matter and fluid from a mixture with a filter medium in which only the fluid can pass
  2. 2. The quantity of matter in the object; determined by weighing the obect
  3. 5. The phase transition in which liquid turns to solid
  4. 7. The branch of chemistry that applies physics to the study of chemistry
  5. 8. The study of the chemistry of matter and the development of tools to measure properties of matter
  6. 9. Separating a homogeneous mixture composed of 2 substances with different boiling points
  7. 10. A type of heterogeneous mixture that consists of coarse particles visible to the naked eye
  8. 11. The phase transition in which solid turns to liquid; can be used in extricating mixtures that contain 2 substances with different melting points
  9. 16. A substance formed when two or more elements are chemically joined
  10. 17. Occurs when the internal make-up of the matter stays the same
  11. 18. Type of mixture whose composition varies from one position to another
  12. 22. The sedimentation of particles under the influence of the centrifugal force and it is used for separation of superfine suspensions.

  21. 37. An effect only exclusive to colloids: the ability to scatter a beam of light that passes through it.
  22. 38. The phase transition in which gas transforms into solid without passing through the liquid phase
  23. 41. Has indefinite shape but definite volume
  24. 46. Branch of chemistry that studies about inorganic compounds, or compounds that don't contain a C-H bond
