| Question | Answer |
| The study of matter and the changes matter undergoes | Chemistry |
| Anything that occupies space and has mass | Matter |
| Rigid shape, maintains volume, not compressible, no flow | Solid |
| Assumes containers shape, maintains volume, not compressible, has flow | Liquid |
| Assumes containers shape and volume, is compressible, and has flow | Gas |
| A state of matter that has total disorder, much empty space, particles have complete freedom of motion and are far apart | Gas |
| A state of matter that has disorder, particles or clusters of particles are free to move relative to each other and are close together | Liquid |
| A state of matter that has ordered arrangement, particles are in fixed positions and are close together | Crystalline Solid |
| Contain only one material with a fixed composition | Pure Substance |
| Two or more elements bonded together | Compound |
| This type of pure substance is made up of one type of atom and can be combined to make compounds | Element |
| This type of pure substance is made up of one type or molecule or unit and the units contain two or more different kinds of atoms | Compound |
| Consists of two or more pure substances mixed together | Mixture |
| A mixture made of multiple substances whose presence can be seen and the portions of its sample have different compositions and properties | Homogeneous |
| A mixture made of multiple substances, but appears to be one substance, and all portions of an individual sample have the same composition and properties | Heterogeneous |
| Bronze | Solution(Solid)/Homogeneous Mixture/Alloy Mixture/ |
| Pepperoni Pizza | Heterogeneous Mixture |
| Maple Syrup | Solution |
| Steel Pipe | Solution |
| Carbon Monoxide | Pure Substance/Compound |
| Arsenic | Pure Substance/Element |
| Vegetable Oil | Solution/Homogeneous Mixture |
| Properties that can be observed without changing a substance into another substance | Physical Properties |
| Properties that can only be observed when a substance is changed into another substance | Chemical Properties |
| Changes that alter the state or appearance of the matter without altering the composition | Physical Changes |
| Changes that alter the composition of the matter (Atoms are rearranges, old bonds break and new bonds form) | Chemical Changes |
