States of Matter: Solid, Liquid, and Gas Molecular Structure Explained #3799143 (License: Personal Use)

The image displays green spherical particles representing molecules in three cylindrical containers. In the solid state (left), particles are tightly packed in a fixed, ordered lattice. In the liquid state (middle), particles remain close but can slide past one another, allowing flow. In the gas state (right), particles are widely spaced and move freely and randomly throughout the container volume.

This image is commonly used in K-12 science curricula, introductory chemistry resources, and educational websites to teach phase changes and kinetic molecular theory. It serves users seeking foundational understanding of matter behavior.
