- 5. a property of a substance that depends on the amount of the substance that is present
- 7. ratio of quantities used to convert between different units
- 9. a property of a substance that is independent of the amount of substance that is present
- 10. a substance that is uniform in composition throughout
- 13. estimate of the difference from the measurement to the true value
- 14. realm of things that are too small to be sensed directly by human senses
- 15. (factor-label method) an organized way to convert from simple to complex units in a mathematical equation
- 16. the law that states that as matter converts from state to state, there is no detectable change in the amount of matter present
