Properties and States of Matter

3. a change that occurs when one or more substances change into entirely new substances with different properties
5. a characteristic of a substance that does not involve a chemical change, such as density, color, or hardness
6. homogeneous mixtures whose particles are smaller than the particles in suspensions but larger than particles in solutions and the particles do not settle out
9. a homogeneous mixture that appears to be a single substance
11. the law that states that mass cannot be created or destroyed in ordinary chemical and physical changes
14. heterogeneous mixture with large particles that can separate and settle out
16. a substance that cannot be separated or broken down into simpler substances by chemical means
17. a pure substance that is composed of molecules that form when two or more kinds of atoms bond
18. anything that has mass and takes up space

1. a property of matter that describes a substance's ability to participate in chemical reactions
2. a change of matter from one form to another without a change in chemical properties
4. the state of matter in which the volume and shape of a substance are fixed
7. the state of matter that has a definite volume but not a definite shape
8. building blocks of matter because they combine with one another to make may different materials
10. a state of matter that starts as a gas and then becomes ionized; it consists of free-moving ions and electrons, it takes on an electric charge, and its prperties differ from those of a solid, liquid, or gas
12. a form of matter that does not have a definite volume or shape
13. matter that contains two or more pure substances
15. the amount of force exerted per unit area of a surface
