Water Phase Change Diagram - Solid, Liquid, and Gas States #3069233 (License: Personal Use)

This scientific illustration depicts the three physical states of water-solid (ice), liquid (water), and gas (steam)-in sequential test tubes, with red arrows labeled “Heat” indicating energy input driving each phase transition. The left tube shows ice cubes melting into liquid water in the middle tube, which then boils into steam with visible vapor waves and bubbles in the right tube. Each state is clearly labeled beneath its respective tube for educational clarity.

Used in educational websites, science curricula, or chemistry resources to explain states of matter and phase transitions; matches user intent for learning or teaching basic thermodynamics and physical changes.
