- 13. the substance that something dissolves into
- 14. the ability to disperse evenly into another substance
- 15. how much space something takes up
- 19. a change in which a new substance is formed (a gas or a solid precipitate); often accompanied by a change in color or odor, i.e., burning, rusting, rotting, etc. (flammability, toxicity, oxidation, etc.) The new substance may be a gas or a solid precipitate
- 21. responsiveness to magnetic forces (i.e., behaving like a liquid in the solid state)
- 22. the main unit for measuring mass/weight; can be multiplied into kilograms or divided into milligrams; measured using a balance
- 24. the main unit for measuring volume; can be divided into milliliters; measured using a graduated cylinder (displacement) or the length x width x height formula
- 25. a combination of two or more different substances in which the substances keep their identities; can be separated by physical methods (i.e., taking them apart)
- 28. a characteristic of matter that can be observed or measured directly (size, shape, color, texture, etc.)
- 29. the phase/state of matter with no definite shape and no definite volume; takes the size and shape of its container
- 32. the substance that dissolves into the solvent
- 33. to become evenly dispersed into another substance such that it seems to disappear
- 35. the temperature at which a substance changes from a liquid to a solid
- 38. the ability to transfer electricity
- 39. a characteristic that can be seen when a substance undergoes a chemical change
- 40. state/_____ (of matter): the size and shape of molecules/particles in a substance (determined by the amount of energy in the substance, as well as whether energy is flowing in or out)
- 42. a tool for measuring mass/weight
- 43. the phase/state of matter with a definite volume, but no definite shape; takes the shape of its container
- 44. anything that has weight and takes up space
- 47. a solid substance that has been separated from a liquid during a chemical process
- 48. a one-meter-long stick (like the one we used as a flagpole during the fun run)

- 16. how easily something can be bent or dented
- 17. the ability to bend without breaking
- 18. the fact that the amount of matter stays the same even when it undergoes physical or chemical changes—“Matter can be neither created nor destroyed.”
- 20. molecule/________: chunks of atoms bonded together; the smallest unit of matter
- 23. how much energy (heat) is in a substance
- 26. how tightly packed the molecules/particles are in a substance
- 27. also called “weight”; the amount of “stuff” that is in something
- 29. a tool for measuring volume using the displacement of water
- 30. the mixture of the solvent and solute; a mixture that has the same composition throughout because its parts are mixed evenly (usually liquids; sometimes gases)
- 31. a chart that shows the freezing, melting, and boiling points of a substance
