  1. 4. numbers 1,2,3,4,5,6,7, 8, 9 are examples of this digits.
  2. 5. When heated the liquid state turns into gas.
  3. 6. It is the quantity of matter in the object.
  4. 7. Has no definite volume and shape and particles are far apart from each other.
  5. 10. Consist of a dispersed phase or the substance that is dissolved or scattered and a dispersing medium.
  6. 12. The process wherein gas turns to liquid.
  7. 16. is the process of simplifying a very large number or a very small number and is used to express multidigit numbers involving many zeros in compact form.
  8. 22. A process in which the mixture is boiled causing the vapors of the two liquids to form at different temperatures.

  10. 26. the _______ for the exponential term is equal to the number of places the decimal point has been moved.
  11. 27. It is another method of separating complex mixture, sometimes with the use of paper.
  12. 30. The dissolving medium in a solution.
  13. 32. are the digits in any measurement that are known with certainty with an additional one digit which is uncertain.
  14. 33. They have definite volume and shape and particles are very close to each other.
  15. 36. This is what you call the liquid that passes through the strainer.
  16. 41. The ability to scatter a beam of light that passes through it.
  17. 42. Are all subject to uncertainty.
  18. 43. the ______ properties of matter are those that can be measured and observed without changing the composition of the substance
  19. 44. Is determined when a certain quantitative value is relatively close to the "true" value.
  20. 45. Is the ratio of the mass of an object to the volume it occupies.
  21. 46. Turning of water into Ice.
  22. 47. It is the consistency of a result.
  23. 49. Happens when an ice turns into a liquid state.
  24. 50. Is a matter that has a definite composition and distinct properties.
Down
  1. 1. The solid particles are allowed to settle first in the bottom and later the liquid is poured into another container leaving behind the liquid particles.
  2. 2. A pure substance containing two or more kinds of atom chemically combined in a definite proportion by mass.
  3. 3. Is also called a solution, it is relatively uniform in composition.
  4. 5. Is the simplest form of matter since it is composed of only one atom.
  5. 8. Consists of coarse particles which are visible to the naked eye.
  6. 9. Also known as extensive Physical property and can be affected by the size and amount of samples.
  7. 11. The dissolved substance in a solution.
  8. 13. A type of error that results from the effects of uncontrolled variables in the measurement
  9. 14. Whether the substance can be easily decomposed or not.
  10. 15. Are composed of two or more substances combined physically in variable proportions.
  11. 17. The mixture is poured into a special tube called centrifuge apparatus, and is allowed to spin using centrifugal force.
  12. 18. A mixture whose composition varies from one position to another within the sample.
  13. 19. tells how hot or cold an object is.
  14. 20. whether the substance undergoes combustion or not.
  15. 21. Whether the substance can damage an organism or not.

  20. 31. The _______ property of matter is the ability of a substance to react with other substances such as air, water, acid and base.
  21. 32. A type of error that results from other uncertainties that may come from a flaw in the equipment used or the design of the experiment.
  22. 34. Also called the Intrinsic Physical Property which does not depend on the size or amount of sample
  23. 35. Is a process of separating the components of a suspension.
