  1. 2. a property that any characteristic of matter that does not depend on the amount of the substance present.
  2. 3. some substances are attracted to a magnet field and can be "pulled" from a mixture
  3. 8. one billionth of a gram.
  4. 9. branch of chemistry. The study of the chemistry of matter and the development of tools to measure properties of matter
  5. 10. is a decimal multiple of the base metric (SI) measurement unit of length, the meter. It stands for trillion.
  6. 11. rules that significant figures have
  7. 14. separation by particle size. The particle size of substances can be very different. Passing a mixture through a screen or filter will allow the small particles to pass and be separated from the larger particles that get trapped.
  8. 15. the branch of chemistry that applies physics to the study of chemistry, which commonly includes the applications of thermodynamics and quantum mechanics to chemistry
  9. 16. also metric unit of length, equal to one tenth of a meter.
  10. 23. is that measuring that property must lead to a change in the substance’s chemical structure.
  11. 27. consists of two or more different elements and/or compounds physically intermingled and often remains many of the properties of its component.
  12. 30. is not a common state of matter here on Earth. It consists of highly charged particles with extremely high kinetic energy.
  13. 31. is a derived metric measurement unit of volume with sides equal to one centimeter (1cm).
  14. 33. is the SI base unit of time.
  15. 35. everything that takes up space and has mass
  16. 36. separation of solids by density different. When put into water, some substances will sink while others will float.
  17. 41. also known as freezing, is a phase change of matter that results in the production of a solid.
  18. 47. separation by particle size. If the mixture is made up of large enough particles, or pieces, you can separate them by hand or tool.
  19. 49. separation of liquids by density and solubility. Given enough time, mixtures of liquids of different densities and solubility will form layers. The top layer can be skimmed off or siphoned, and the bottom layers can be removed via a siphon or mechanical means.
  20. 50. a metric unit of length, equal to one hundredth of a meter.
  21. 52. figures
  22. 53. A unit of mass equal to 1012 (one trillion) grams.

  1. 1. is the standard unit of mass in the SI system.
  2. 4. branch of chemistry. The study of compounds not covered by organic chemistry; the study of inorganic compounds, or compounds that don't contain a C-H bond (many inorganic compounds contain metals)
  3. 5. when a solid is converted directly into a gas without going through a liquid phase
  4. 6. occurs when a gas loses energy and comes together to form a liquid.
  5. 7. holds a definite shape and volume without a container. The particles are held very close to each other
  6. 10. is an intensive property.
  7. 12. separation by solubility. Substances have different solubilities at temperature
  8. 13. a compressible fluid. Not only it will conform to the shape of its container but it will also expand to fill the container.
  9. 17. consists of only one kind of atom and can exist as either atoms or molecules.
  10. 18. is a branch of science that deals with the form and properties of matter and substances or the interaction between individuals.
  11. 19. a metric unit of capacity, formerly defined as the volume of one kilogram of water.
  12. 20. (Elements, compound and mixtures)
  13. 21. are properties that can be measured or observed without changing the chemical nature of the substance.
  14. 22. is a decimal multiple of the base metric (SI) measurement unit of length, the meter. It stands for billion.
  15. 24. a property that any characteristic of matter that depends on the amount of matter being measured.
  16. 25. is the conversion of a liquid to a gas and can occur through either evaporation or boiling.
  17. 26. consists of atoms of two or more different elements bound together and always contains the same ratio of its component atoms.
  18. 28. base units in the SI system
  19. 29. is the process by which a substance changes from the solid phase to the liquid phase.
  20. 32. is the SI unit of temperature
  21. 34. of separating mixtures
  22. 37. are standards of comparison for measurements
  23. 38. consists of two or more atoms of the same element, or different elements, that are chemically bound together
  24. 39. system A series of units that is accepted and used throughout the scientific world.
  25. 40. figures are any non-zero digits or trapped zeros.
  26. 42. separation by inner molecular attractions. Some mixtures have components that "stick" to materials in different ways.
  27. 43. separation by boiling point differences.
  28. 44. branch of chemistry. The study of carbon and its compounds; the study of the chemistry of life
  29. 45. occurs when a gas transforms directly into a solid, without going through the liquid phase.
  30. 46. is the standard unit of length in both the SI and original metric
  31. 48. the study of chemical processes that occur inside of living organisms
  32. 51. a mostly non-compressible fluid. Able to conform to the shape of its container but retains a (nearly) constant volume independent of pressure
