Worksheet: The Properties of Solids, Liquids and Gases

We are given a list of properties and need to tick the correct state(s) they apply to:

- S = Solid
- L = Liquid
- G = Gas

> Hint: Two states might share the same property!

✔ Step-by-step Analysis

1. It will mould its shape to its container
- Liquids (L) and Gases (G) take the shape of their container.
- Solids keep their own shape.
→ Tick: L, G

2. It will spread out on a surface
- Liquids (L) spread out (e.g., water on a table).
- Gases (G) also spread out to fill space.
- Solids do not spread out.
→ Tick: L, G

3. It will hold its shape unless broken
- Only Solids (S) maintain their shape.
→ Tick: S

4. It does not flow
- Solids (S) do not flow.
- Liquids and gases do flow.
→ Tick: S

5. It can be compressed
- Gases (G) are easily compressed.
- Liquids and solids are nearly incompressible.
→ Tick: G

6. Its particles are free to move past each other
- Liquids (L) and Gases (G) have particles that can move past each other.
- Solids have fixed positions.
→ Tick: L, G

7. There is lots of space between each particle
- Gases (G) have large spaces between particles.
- Solids and liquids have particles close together.
→ Tick: G

8. Its particles are in contact with one another
- Solids (S) and Liquids (L) have particles in contact.
- Gases have particles far apart.
→ Tick: S, L

9. It can flow
- Liquids (L) and Gases (G) flow.
- Solids do not.
→ Tick: L, G

10. Its particles are not in contact with one another
- Only Gases (G) have particles far apart and not touching.
→ Tick: G

11. Its particles cannot move past each other
- Solids (S) have fixed particles — they vibrate but don't move past each other.
→ Tick: S

12. There is little space in-between each particle
- Solids (S) and Liquids (L) have particles close together.
- Gases have large gaps.
→ Tick: S, L

🎨 Drawing the Particles

Now, draw a simple representation of particles in each state:

#### Solid
- Particles are close together, arranged in a fixed pattern (like a grid).
- They vibrate in place, but do not move around.
- Draw small circles tightly packed in a regular pattern.

```
[•] [•] [•]
[•] [•] [•]
[•] [•] [•]
```

#### Liquid
- Particles are close together, but not in a fixed pattern.
- They can slide past each other.
- Draw circles close together but randomly arranged.

```
[•] [•] [•]
[•] [•] [•]
[•] [•] [•]
```
(But slightly less ordered than solid — maybe some overlap or irregular spacing)

#### Gas
- Particles are far apart, moving freely.
- Large spaces between them.
- Draw a few circles scattered across the box with big gaps.

```
[•] [•]
[•] [•]
[•]
```

✔ Summary

This worksheet helps understand how the arrangement and movement of particles determine the physical state.

✔ Key Concepts:
- Solids: Fixed shape, particles close and vibrating.
- Liquids: Take container shape, particles close but mobile.
- Gases: Fill container, particles far apart and fast-moving.
