Across
- 1. energy: the total kinetic energy of a substance's particles
- 4. the amount of force exerted per unit area of a surface
- 5. a substance made up of atoms of two or more different elements joined by chemical bonds
- 8. fundamental building blocks (like chemical elements: Oxygen, Gold) or basic parts of a whole
- 9. of State: the change of a substance from one physical state to another
- 10. Substance: a sample of matter, either a single element or a single compound, that has definite chemical and physical properties
- 11. a measure of the amount of matter in an object
- 13. 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
- 15. The amount of space that an object takes up, or occupies
- 17. the smallest unit of an element that maintains the properties of that element
Down
- 1. a measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object
- 2. a form of matter that does not have a definite volume or shape
- 3. table: a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.
- 6. anything that has mass and takes up space
- 7. Density is how much mass is packed into a certain volume
- 12. The state of matter in which the volume and shape of a substance are fixed
- 14. Bond: the force holding atoms or ions together to form molecules, crystals, and compounds
- 16. the state of matter that has a definite volume but not a definite shape
