A phase behavior diagram is a graphical representation of the relationship between pressure, temperature, and the phases of a substance. It shows the boundaries between the different phases (solid, liquid, gas) and the conditions at which phase transitions occur.
1. Critical point: The critical point on a phase behavior diagram represents the highest temperature and pressure at which a substance can exist as a distinct liquid and gas phase. At the critical point, the distinction between the liquid and gas phases disappears, and the substance becomes a supercritical fluid. The critical point is denoted by a specific temperature and pressure on the phase diagram.
2. Bubble point curve: The bubble point curve on a phase behavior diagram represents the conditions at which a liquid phase begins to vaporize into a gas phase. It is the curve that separates the two-phase region (liquid and gas coexisting) from the single-phase region (either all liquid or all gas). The bubble point curve shows the temperature and pressure at which the first bubble of gas forms in a liquid.
3. Dew point curve: The dew point curve on a phase behavior diagram represents the conditions at which a gas phase begins to condense into a liquid phase. It is the curve that separates the two-phase region (liquid and gas coexisting) from the single-phase region (either all liquid or all gas). The dew point curve shows the temperature and pressure at which the first droplet of liquid forms in a gas.
4. CricondenTherm: The CricondenTherm point on a phase behavior diagram represents the highest temperature at which a substance can exist in a single-phase region. It is the point where the bubble point curve and dew point curve intersect, indicating the maximum temperature for a substance to remain in a single phase.
5. CricondenBar: The CricondenBar point on a phase behavior diagram represents the highest pressure at which a substance can exist in a single-phase region. It is the point where the bubble point curve and dew point curve intersect, indicating the maximum pressure for a substance to remain in a single phase.

Phase Behavior Diagram
A phase behavior diagram is a graphical representation of the thermodynamic conditions (temperature and pressure) at which different phases of a substance (e.g., liquid, gas, solid) coexist in equilibrium.
Critical Point
- The critical point is the unique point on the phase behavior diagram where the liquid and gas phases become indistinguishable.
- Above the critical point (temperature and pressure), the substance exists only as a single homogeneous phase called a "supercritical fluid."
- At the critical point, the boundary between the liquid and gas phases disappears, and they have identical properties (e.g., density, viscosity).
Bubble Point Curve
- The bubble point curve represents the conditions at which a small gas bubble first appears in a liquid.
- Below the bubble point curve, the substance is entirely liquid.
- As the temperature or pressure is increased along the bubble point curve, more gas bubbles form and eventually the substance becomes a two-phase mixture of liquid and gas.
Dew Point Curve
- The dew point curve represents the conditions at which a small liquid droplet first condenses from a gas.
- Above the dew point curve, the substance is entirely gas.
- As the temperature or pressure is decreased along the dew point curve, more liquid droplets condense and eventually the substance becomes a two-phase mixture of liquid and gas.
CricondenTherm
- The cricondentherm is the point on the phase behavior diagram where the liquid-liquid and gas-liquid equilibrium lines meet.
- This point represents the highest temperature at which two liquid phases of different compositions can coexist in equilibrium.
CricondenBar
- The cricondenbar is the point on the phase behavior diagram where the liquid-liquid and gas-liquid equilibrium lines meet.
- This point represents the lowest pressure at which two liquid phases of different compositions can coexist in equilibrium.
