**Phase Diagram for Water**This diagram illustrates the different phases of water—solid, liquid, and vapor—at various temperatures and pressures. It is a crucial tool for understanding the behavior of water under different conditions.**Parts of the Diagram:**1. **Axises**: - **X-Axis (Temperature in °C)**: Ranges from approximately -79°C to 374°C. - **Y-Axis (Pressure in kPa)**: Ranges from 0.13 kPa to 22,100 kPa.2. **Critical Points**: - **A**: Represents the lower boundary of the solid phase. - **B (Triple Point)**: The point at which solid, liquid, and vapor phases coexist. It is marked at approximately 0.01°C and 0.611 kPa. - **C**: The boundary line starting from the solid phase towards higher pressure. - **D**: Represents the critical point for vaporization, beyond which the liquid and vapor phases are indistinguishable.3. **Phase Regions**: - **Solid**: Found at lower temperatures and higher pressures. - **Liquid**: Exists between the solid and vapor phases, across a range of temperatures and pressures. - **Vapor**: Present at higher temperatures and lower pressures.4. **Key Temperatures**: - **T\(_m\)**: Melting point line, showing the transition from solid to liquid. - **T\(_b\)**: Boiling point line, indicating the transition from liquid to vapor.This phase diagram is an essential reference for understanding water's physical properties and the conditions under which phase transitions occur.

What unusual fact about water does this reflect?**---This worksheet provides questions related to the phase diagram of water, focusing on concepts such as equilibrium, triple points, and the unique properties of water as observed in its phase changes. The worksheet seems to be designed to test knowledge and understanding of how water transitions between its solid, liquid, and gaseous states under varying temperatures and pressures, as well as familiarizing students with critical points on the phase diagram.

Given phase diagram of water. Phase diagram is the graphical representation of the physical states of the substance under different conditions of temperature and pressure. Phase diagram has pressure on the Y-axis and temperature on the X-axis. When lines or curves are crossed on the phase diagram then phase changes can be observed.1. In the phase diagram for water, temperature is plotted on X-axis and pressure is taken on Y-axis. 2. The lines on the phase diagram represent the combination of pressure and temperatures at which two phases can exist in equilibrium. Line AB represents the transition between solid (ice) and gaseous (water vapor) phases. It is called sublimation curve of water. This curve represents at that particular temperature and pressure both the solid and gaseous phase of water are in equilibrium.3. Curve BD represents the transition between liquid and vapor phase. It is called vaporization or condensation curve. 4. Line BC represents the transition between solid and liquid phase of water. Both the phases will be at equilibrium under those pressure and temperature. It is called fusion curve.5,7. Point B called triple point of water. At this (pressure and temperature) point all the three phases solid, liquid and gaseous phases of water will coexist or in equilibrium. Temperature at the triple point of water is 0.01oC and pressure is 0.611KPa. 6. Point D is called critical point. The temperature corresponding to this is called critical temperature. The temperature above which a gas cannot be liquified only by applying pressure.8. The normal melting point of ice is 0oC at 1 atm or 101.325kPa pressure. 9. The normal boiling point of water is 100oC at 1 atm or 101.325kPa pressure. 10. Pressure 101.325kPa is equal to one atmosphere pressure. 11. The slope of the solid-liquid equilibrium line of water is negative. This represents that liquid phase is more denser than solid phase of water. The reason for this is volume of ice is greater than volume of water. Because of this property of H2O, it can be melted by applying pressure and not by adding heat.
