Across
  1. 5. a property of a substance that depends on the amount of the substance that is present
  2. 7. ratio of quantities used to convert between different units
  3. 9. a property of a substance that is independent of the amount of substance that is present
  4. 10. a substance that is uniform in composition throughout
  5. 13. estimate of the difference from the measurement to the true value
  6. 14. realm of things that are too small to be sensed directly by human senses
  7. 15. (factor-label method) an organized way to convert from simple to complex units in a mathematical equation
  8. 16. the law that states that as matter converts from state to state, there is no detectable change in the amount of matter present
Down
  1. 1. a behavior/property that changes between states of matter
  2. 2. a substance that varies in its composition
  3. 3. gaseous state of matter containing many electrically charged atoms/molecules
  4. 4. smallest particle of an element that can combine chemically
  5. 6. special symbols used to represent microscopic/macroscopic domains (Ex: chemical symbols, formulas/equations and graphs)
  6. 8. everyday things that are large enough to sense by human senses
  7. 11. collection of two or more atoms of the same or different element
  8. 12. a change that produces a different state of matter than the original
