Read each question carefully and answer to the best of your ability. Good luck!
Everything around us is made of matter. Matter can be found in three main states: solid, liquid, and gas. Each state has different properties.
Solids have a definite shape and volume. Their particles are packed closely together. Liquids have a definite volume but no definite shape; they take the shape of their container. Their particles are close but can move past each other. Gases have no definite shape or volume; they spread out to fill any container. Their particles are far apart and move freely.
