## Answer key

1. **B.** Gas particles are separated by large spaces and move constantly in all directions, which is the defining feature of the gaseous state.

2. **Attractive forces hold the particles together tightly in a solid.** In solids, these forces are strongest, which is why particles vibrate in place rather than moving freely.

3. **True.** The particle model states that all matter is made up of small particles with spaces between them.

4. **1 g/mL** (or 1 gram per millilitre). Density is mass divided by volume, so 500 g ÷ 500 mL = 1 g/mL.

5. **In a liquid, particles are separated by spaces and can slide past each other. In a gas, particles are separated by much larger spaces and move constantly in all directions.** Liquids have closer particles with weaker attractive forces than solids, while gases have the most space and movement.

6. **C.** Solids have the strongest attractive forces between particles, which keeps them rigid and fixed in shape.
