States of Matter: Solid, Liquid, and Gas Explained Visually #3836226 (License: Personal Use)

The image displays three identical transparent cylinders, each containing green spherical particles representing atoms or molecules. In the solid state, particles are arranged in a fixed, closely packed lattice; in the liquid state, they remain in contact but move freely past one another; in the gas state, particles are widely dispersed and move independently throughout the container. This visual effectively conveys key differences in density, shape retention, and compressibility across states.

Commonly used in middle school and high school science curricula, educational websites, and introductory chemistry resources to teach phase changes and kinetic molecular theory. Matches user intent for visual learning, quick reference, or classroom instruction on matter fundamentals.
