| Question | Answer |
| Mass | A measure of the amount of matter in an object |
| Mass | A measure of the amount of matter in an object |
| Volume | Amount of space occupied by an object |
| Substance | A single kind of matter that is pure and has a specific set of properties |
| Physical Property | A characteristic of a pure substance that can be observed without changing it into another substance |
| Solid | Definite shape and volume |
| Liquid | A state of matter that has no definite shape but has a definite volume |
| Gas | A state of matter with no definite shape or volume |
| Vapor | Liquid to gas |
| Physical Change | A change in a substance that does not involve a change in the identity of the substance |
| Mixture | A combination of two or more substances that are not chemically combined |
| Heterogenous Mixture | A mixture with uneven distribution of different substances, solids, liquids, gases. |
| Homogenous Mixture | a mixture in which two or more substances are evenly mixed on the atomic level but not chemically bonded |
| Solution | A homogeneous mixture of two or more substances |
| Filtration | The process that separates a solid from a liquid or gas |
| Distillation | A liquid is boiled to produce a vapor that is then condensed into a pure liquid |
| Element | Simplest form of matter that has a unique set of properties |
| Compound | A substance made up of atoms of two or more different elements joined by chemical bonds |
| Chemical Change | Change that produces matter with a different composition than the original matter |
| Chemical Symbol | One or two letter representation of an element |
| Chemical Property | Ability of a substance to undergo a specific chemical change (e.g., hydrogen reacts w/ oxygen to produce water) |
| Chemical Reaction | When one or more substances change into one or more new substances |
| Precipitate | Insoluble solid that may emerge from a liquid mixture during a chemical reaction |
| Law of Conservation of Mass | Matter is neither created nor destroyed in any physical change or chemical reaction |
| Plasma | A gas-like state of matter consisting of a mixture of free electrons and positively charged nuclei. The most common state of matter in the Universe. This state exists in fusion reactions (ie., stars), lightning bolts, and fluorescent lights. |
| density | A measure of how much mass is contained in a given volume |
| compressibility | A measure of how much the volume of a sample decreases under pressure |
| conductivity | The ability of an object to transfer heat or electricity to another object |
| malleability | A measure of how well a substance can be hammered or beaten into a new shape without shattering |
| ductility | A measure of how well a substance can be drawn, pulled, or extruded through a small opening to produce a wire |
| reactivity | How readily a substance combines chemically with other substances. |
| freezing point | The temperature at which a liquid changes into a solid |
| boiling point | The temperature at which a liquid completely changes to a gas |
| evaporation | The change of a substance from a liquid to a gas below its boiling point |
| condensation | The change from a gas to a liquid |
| deposition | Change from a gas directly to a solid |
| melting | The change from a solid to a liquid |
| sublimation | A change directly from the solid to the gaseous state without becoming liquid |
| chromatography | A technique that is used to separate the components of a mixture based on the tendency of each component to travel through, or be drawn across the surface of, another material. |
