Across
- 1. The total kinetic energy of a substance
- 3. the state of matter in which the volume and shape of a substance are fixed
- 6. a measure of the amount of matter in an object
- 8. a substance that cannot be separated or broken down into simpler substances by chemical means
- 10. a measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object
- 15. the force holding atoms or ions together to form molecules, crystals, and compounds, driven by atoms seeking a lower, more stable energy state by sharing or transferring electrons
- 16. The amount of force exerted per unit area of a serfice
- 17. a substance made up of atoms of two or more different elements joined by chemical bonds
Down
- 2. a form of matter that does not have a definite volume or shape
- 4. how much mass is packed into a certain volume, calculated by dividing mass by volume
- 5. the amount of space that an object takes up, or occupies
- 6. anything that has mass and takes up space
- 7. a group of atoms that are held together by chemical forces; a molecule is the smallest unit of a compound that keeps all the properties of that compound
- 9. The change of substance from one state to another
- 11. a sample of matter, either a single element or a single compound, that has definite chemical and physical properties
- 12. the smallest unit of an element that maintains the properties of that element
- 13. A chart the organizes all the known elements.
- 14. the state of matter that has a definite volume but not a definite shape
