Across 2. Material that exists because it has mass and occupies space 7. "______ properties" describe the activity and/or behavior of a substance when combined with other substances 9. The relationship between a substances mass and volume 10. State of matter with no definite shape or volume 13. Propertiy that describes the amount of space an object occupies 14. Numerical representation of a measurement's reliability/quality 16. Mixture with uniform properties making individual particles indistinguishalbe 17. Mixtures that are not uniform in composition such that individual particles can be distinguished 19. A means to measure the amount of matter an object contains 20. State of matter with neither definite shape or volume BUT can be organized into other states under "normal" conditions 22. Process used to physicaly separate a mixture of liquids based on different vaporization temperatures 24. Describes how close a measurement comes to the true/expected value 25.
