Melting (or freezing) curve

Melting (or freezing) curve – the curve on a phase diagram which represents the transition between liquid and solid states. It shows the effect of pressure on the melting point of the solid. Anywhere on this line, there is equilibrium between the solid and the liquid.

2. The blue line divides the liquid and gas phases, and represents vaporization (liquid to gas) and condensation (gas to liquid) points.

Vaporization (or condensation) curve – the curve on a phase diagram which represents the transition between gaseous and liquid states. It shows the effect of pressure on the boiling point of the liquid. Anywhere along this line, there will be equilibrium between the liquid and the vapor.

3. The red line divides the solid and gas phases, and represents sublimation (solid to gas) and deposition (gas to solid) points.

Sublimation (or deposition) curve – the curve on a phase diagram which represents the transition between gaseous and solid states. It represents the effect of increased temperature on a solid at a very low constant pressure, lower than the triple point.
