7. States of Matter
7.1 Particle Theory, Arrangement and movement of particles
Discover How Tiny Particles Make Up Everything Around You
You will explore particle theory and learn how the arrangement and movement of particles explain why solids, liquids, and gases behave the way they do.
What You'll Learn
You will learn all matter is made of tiny moving particles.
You will discover how particles arrange differently in each state.
You will understand how energy causes particles to change states.
You will connect particle theory to real-world science topics.
What You'll Practice
1
You will identify how particles move in solids, liquids, gases.
2
You will explain why matter changes state using particle theory.
3
You will compare particle arrangement and energy across all states.
Why This Matters
Understanding particle theory gives you the foundation to explain how and why matter behaves the way it does in every state from the ice in your drink to the air you breathe.
