Saturation Liquid Phase Range
The saturation liquid phase is the state where a liquid is about to vaporize. Its existence is bounded by specific thermodynamic points:
- Triple Point: This is the unique temperature and pressure where solid, liquid, and vapor phases coexist in equilibrium. Below the triple point's pressure, a stable liquid phase cannot exist.
- Critical Point: This is the temperature and pressure beyond which the distinct liquid and vapor phases cease to exist, merging into a supercritical fluid.
Therefore, the saturation liquid phase, along with its corresponding saturation vapor phase, can only exist within the pressure and temperature range between the triple point and the critical point on a substance's phase diagram.
The correct option is 3, indicating the range from the triple point to the critical point.
