  15. 30. are independent from the base unit modify and always remain constant.
  16. 31. is another method of seperating complex mixtures.
  17. 33. a type of property of matter which is the ability of a substance to react with other substances such as air, water, acid, and base.
  18. 36. solid to gas.
  19. 37. ANALYSIS, is a process in which a conversion factor which is writtin in a form of ratio is used to change the units given in the data to the units desired.
  20. 39. is anything that has mass and occupies space.
  21. 42. also called extrinsic property, this is those that can be affected by the size and amount of samples.

  25. 48. is of a process of seperating the components of a suspension.
  26. 49. whether the substance undergoes combustion or not.

  1. 1. the particles also move quickly in all directions. It can fill up any container of any shape and size and can be compressed because of the distances of their molecules from one another.
  2. 3. the solid particles are allowed to settle first at the bottom and later, the liquid is poured into another container leaving behind the solid particle.
  3. 5. type of property of matter than can be measured and observed without changing the composition of the substance.
  4. 7. is the simplest form of matter since it is composed of only one kind of atom.
  5. 8. a mixture whose composition varies from one position to another within the sample is considered as it.
  6. 9. is a colloidal suspension of particles dispersed in gas.
  7. 12. ERROR, is a flaw in the experiment or the design of the experiment.
  8. 15. their particles are closed together; hence cannot be compressed and cannot move freely from place to place. This has a fixed shape.
