What's Happening?
🧊 Solid
Particles are packed tightly in a regular pattern. They vibrate in place but cannot move past each other. This gives solids a FIXED SHAPE.
💧 Liquid
Particles are close together but can SLIDE past each other. Liquids flow and take the SHAPE OF THEIR CONTAINER but have a fixed volume.
💨 Gas
Particles are FAR APART and zoom around in all directions. Gases spread out to FILL ANY SPACE and can be compressed.

🤯 Did You Know?
- • Water is unusual — ice (solid) is LESS dense than liquid water, so it floats!
- • At absolute zero (-273°C), particles almost stop moving completely.
- • There's actually a 4th state called PLASMA — it's what stars are made of!
