Particles are everywhere.
You cannot see particles but you can smell them in the air.
Particle are very small, and you cannot see them.
Gas particles are spread out.
Because the particles are close together and in a fixed position.
Because the particles vibrate.
Because the particles are solid.
Because it does not move.
You can move through air.
You cannot see a gas.
Gas particles are constantly moving in all directions.
You can compress a gas and "squeese" a particle together.
Solid particles are close together and vibrate
Ice is better than water
Ice particles are less dense than water particles.
Ice and water do not mix
It has a defined shape.
The particles slide past each other
It undergoes a phase change.
When a gas evaporates.
When water turns to ice.
When a solid turns into a liquid.
Any time matter changes into a solid, a liquid or a gas.
Whether the substance has a fixed shape.
Weather the substance has a fixed volume
The state of matter of the substance
The kinetic energy of the particles in the substance
Its particle ate locked in place but can pass through each other.
Its particles ate far apart and occasionally bounce into each other.
Its particles are close together and slide past each other.
It does not have particles.
Solid, liquid, gas
Gas, solid, liquid
Gas, liquid, solid

Particles in ice move slow but particles in hot water move fast.
Ink will mix faster in hot water that in cold water.
When popcorn is cold you cannot smell the particles, when you heat it, you can smell the particles.
Tea made hot water spreads the particles (and the flavor) better than cold water.
