Particle Theory of Matter

Particles in different states of matter

🔬 Part 1: Understanding Particles

1. What is matter made of?

Large blocks that we can see

Tiny particles that are too small to see

Only water and air

Nothing - matter is empty space

2. In which state of matter are particles packed most closely together?

Solid

Liquid

Gas

All states are the same

3. Which statements about particles in gases are correct? (Tick all that apply)

They move very fast

They are far apart from each other

They stay in fixed positions

They can spread out to fill a container

4. Complete this sentence: When particles heat up, they move __________ and when they cool down, they move __________.

📊 Part 2: Particle Behaviour

5. Draw and label how particles are arranged in each state of matter:

Solid:




Liquid:




Gas:




6. Explain why ice (solid water) has a fixed shape, but water (liquid) takes the shape of its container.
7. A student says: "Steam from a kettle disappears because the particles are destroyed." Do you agree? Explain your answer using particle theory.

🌡️ Part 3: Real-World Applications

8. Match each example with the correct particle behaviour:
Ice cube melting
Perfume spreading across a room
Water freezing in the freezer
Steam rising from hot soup
Particles slow down and get closer
Particles speed up and spread out
Particles move faster and escape liquid
Particles gain energy and move more freely
9. Think of one example from your daily life where you can observe particles changing from one state to another. Describe what happens to the particles.
10. One new thing I learned about particles today:
