2. a substance that contains two or more elements chemically combined in a fixed proportion
8. a quality or condition of a substance that can be observed or measured without changing the substance's composition
10. some properties of a material change, but the composition does not
12. a property that depends on the type of matter in a sample, not the amount of matter
17. a vertical column on the periodic table
18. a physical blend of two or more components
19. a change that produces matter with a different composition than the original matter
20. the simplest form of matter that has a unique set of properties
22. a form of matter that has a variable shape, but a fixed volume
24. a mixture in which the composition is not uniform throughout

1. matter that has a uniform and definite composition
3. any part of a sample with uniform composition and properties
4. a property that depends on the amount of matter in a sample
5. describes the gaseous state of a substance that is generally a liquid or solid at room temperature
6. another word for homogeneous mixture
7. a one- or two- letter representation of an element
8. an arrangement of elements in which the elements are separated into groups based on a set of repeating properties
9. a form of matter that has a definite shape and volume
11. a liquid is boiled to produce a vapor that is then condensed into a liquid
13. a measure of the space occupied by the object
14. the process that separates a solid from the liquid in a heterogeneous mixture
15. a form of matter that takes both the shape and volume of its container
16. a horizontal row on the periodic table
21. a measure of the amount of matter the object contains
23. a mixture in which the composition is uniform throughout
