- 1. A state of matter with a fixed shape and volume; its particles are closely packed and have a regular structure.
- 2. A state of matter with a fixed volume but no fixed shape; its particles are more loosely packed than in a solid.
- 4. A subatomic particle found in the nucleus of an atom, with a positive electric charge.
- 6. A process in which substances interact and transform into new substances with different properties.
- 8. The substances formed as a result of a chemical reaction.
- 10. Related to or involving substances and processes in the study of chemistry.
- 13. The mass of an object per unit volume, often used to describe how tightly packed the particles in a substance are.
- 14. A state of matter with no fixed shape or volume; its particles are widely spaced and move freely.
