Across
- 2. A property that does NOT depend on the amount of a substance being measured. If the amount of the substance changes, its intensive properties will NOT change. Ex: density, color, etc.
- 3. A property that describes a characteristic or behavior of a substance that may be observed when it undergoes a chemical change or reaction.
- 9. The branch of chemistry that attempts to solve real world problems with the information and techniques of chemistry.
- 10. A change in the chemical composition of a substance. EX: Burning, rusting, exploding.
- 12. A substance made of two or more different types of atoms bonded together.
- 13. A property that depends on how much of a substance is being measured. If the amount of the substance changes, its extensive properties will change. Ex: Mass, Volume, etc.
- 14. Anything made of atoms, has mass, and takes up space.
Down
- 1. The study of atoms, how atoms interact with one another, and the changes associated with that interaction.
- 4. The branch of chemistry where the theories and techniques of physics are applied to chemistry.
- 5. Any change in the physical state of a substance without altering the chemical composition of that substance. EX: melting, freezing, tearing, crushing, etc.
- 6. The smallest unit of matter. It cannot be broken down further without a nuclear change occurring.
- 7. Any property that describes the physical state of a substance. Can be observed without a chemical change occurring.
- 8. The study of atoms, how atoms interact with one another, and the changes associated with that interaction.
- 11. A substance made of only one type of atoms. Ex: Pure gold
