Phase Diagram of Water

A phase diagram of water illustrates the different states (solid, liquid, gas) under various temperatures and pressures. It shows how water transitions between these states: for instance, ice (solid) melts to become liquid water, and boiling water (liquid) turns into steam (gas). The diagram features lines that represent phase boundaries, where two states coexist, like ice and water at 0°C. The critical point marks the end of distinct liquid and gas phases. This diagram helps us understand conditions where water behaves differently, crucial for fields like chemistry, meteorology, and environmental science.
