States of Matter Phase Change Diagram - Solid, Liquid, Gas Transitions #3578660 (License: Personal Use)

The image depicts three cylindrical containers representing solid (left), liquid (middle), and gas (right) states, with green particles illustrating increasing molecular spacing and kinetic energy. Bidirectional white arrows indicate reversible transitions-melting, freezing, vaporization, condensation-while large curved black arrows emphasize the cyclical nature of phase changes. This schematic is commonly used in physics and chemistry curricula to teach thermodynamic behavior.

Used in educational websites, digital textbooks, and STEM lesson plans to explain phase transitions; matches user intent for visual learning, homework help, or teacher resource searches.
