- Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, while gases fill their container evenly.
- The document explores various properties of matter like occupying space, having mass, and existing in different states depending on the arrangement of particles. It provides examples to illustrate solid, liquid and gas states.
