Particle theory
Particle theory states that everything (solids, liquids, gases) is made of tiny moving particles.
The particles move because of their kinetic energy, which means their moving energy.
How much the particles move depends on their energy and the type of material.
These differences help explain why matter can be solid, liquid, or gas.
Particle theory helps us describe how particles are arranged and move in solids, liquids, and gases.
