SOLUTION: Matter states KS3 worksheet - Studypool - Free Printable

Problem Analysis and Solution

The image provided is a worksheet focused on the states of matter for KS3 (Key Stage 3) students. The tasks involve identifying states of matter, completing a diagram, and comparing properties of different states. Below is a detailed solution to each part of the problem.

#### Task 1: Name the three states of matter and state a particle diagram for each.

The three states of matter are:
1. Solid
2. Liquid
3. Gas

Each state has a distinct arrangement of particles:

- Solid: Particles are closely packed in a fixed, ordered structure. They vibrate but do not move freely.
- Liquid: Particles are close together but can move past one another. They have more freedom than in solids but less than in gases.
- Gas: Particles are far apart and move freely in all directions with no fixed shape or volume.

The diagrams provided correspond to these states:
- Diagram 1 (left): Represents a solid because the particles are tightly packed in a regular, fixed pattern.
- Diagram 2 (middle): Represents a liquid because the particles are close together but not in a fixed pattern, allowing some movement.
- Diagram 3 (right): Represents a gas because the particles are widely spaced and moving freely.

#### Task 2: Complete the diagram below.

The diagram appears to be a flowchart or classification chart for the states of matter. The labels provided are:
- Fixed shape
- Fixed volume
- Particles vibrating
- Particles moving past each other
- Particles moving freely
- No fixed shape
- No fixed volume

We need to match these labels to the appropriate states of matter (solid, liquid, gas).

1. Solid:
- Fixed shape
- Fixed volume
- Particles vibrating (but not moving past each other)

2. Liquid:
- No fixed shape
- Fixed volume
- Particles moving past each other

3. Gas:
- No fixed shape
- No fixed volume
- Particles moving freely

Using this information, we can complete the diagram as follows:
- Top left box: Fixed shape
- Middle left box: Fixed volume
- Bottom left box: Particles vibrating
- Top right box: Particles moving past each other
- Middle right box: No fixed shape
- Bottom right box: No fixed volume

#### Task 3: Tick (√) in the table to show which properties apply to each state.

The table lists properties and asks which states (solid, liquid, gas) exhibit them. The properties are:
1. Fixed shape
2. Fixed volume
3. Partially compressed

We analyze each property for each state:

1. Fixed shape:
- Solid: Yes (√)
- Liquid: No
- Gas: No

2. Fixed volume:
- Solid: Yes (√)
- Liquid: Yes (√)
- Gas: No

3. Partially compressed:
- Solid: No
- Liquid: No
- Gas: Yes (√)

The completed table looks like this:

| Properties | Solid | Liquid | Gas |
|----------------------|-------|--------|-----|
| Fixed shape | √ | | |
| Fixed volume | √ | √ | |
| Partially compressed | | | √ |

Final Answer Summary

1. States of Matter and Diagrams:
- Diagram 1: Solid
- Diagram 2: Liquid
- Diagram 3: Gas

2. Completed Diagram:
- Top left: Fixed shape

- Top right: Particles moving past each other
- Middle right: No fixed shape
- Bottom right: No fixed volume

3. Table:
| Properties | Solid | Liquid | Gas |
|----------------------|-------|--------|-----|
| Fixed shape | √ | | |
| Fixed volume | √ | √ | |
| Partially compressed | | | √ |
