Phase diagram of water Note: for H2O melting point decreases with increasing pressure, for CO2 melting point increases with increasing pressure. WATER Covers ~ 70% of the earth's surface Life on earth depends on water Water is a "universal" solvent Easily polluted; hard to purify.

The AB line is the ice-vapor line, the BC line is the ice-water line, and the BD line is the water-vapor line. We can use the phase diagram to identify the state where water exists under specific temperature and pressure conditions. For example, water is ice at 50 kPa and - 10 o C.

The phase diagram for water is shown in the figure below. Figure 13.20. 1: Phase diagram for water. Notice one key difference between last section's general phase diagram, and the above phase diagram for water: in water's diagram, the slope of the line between the solid and liquid states is negative rather than positive.

In the phase diagram for water, the variation of the vapor pressure of ice with temperature is shown by the line AT. As might be expected, the vapor pressure of ice is quite small, never rising above 0.006 atm (0.61 kPa). The vapor pressure of liquid water is usually much higher, as is shown by the curve TC. The point C on this curve.

English: Phase diagram of water as a log-lin chart with pressure from 1 Pa to 1 TPa and temperature from 0 K to 660 K, compiled from data in [1] and [2]. Note that the phases of Ice X and XI (hexagonal) differ from the diagram in [3]. The SVG code is valid. This diagram was created with an unknown SVG tool.

The phase diagram shows that the water would first freeze to form ice as it crossed into the solid area. When the pressure fell low enough, the ice would then sublime to give water vapor. In other words, the change is from liquid to solid to vapor. Example \(\PageIndex{2}\): Phase Diagram for Carbon Dioxide.

Depiction in Phase Diagram of Water. At different temperatures and pressures, a phase diagram depicts the preferred physical states of matter. Water is a liquid at typical room temperatures and pressures, but it becomes solid (i.e. ice) if the temperature is reduced below 273 K, and gaseous (i.e. steam) if the temperature is increased above 373 K at the same pressure.

Phase diagram is a graphical representation of the physical states of a substance under different conditions of temperature and pressure. A typical phase diagram has pressure on the y-axis and temperature on the x-axis. As we cross the lines or curves on the phase diagram, a phase change occurs. In addition, two states of the substance coexist.

As we increase the temperature, the pressure of the water vapor increases, as described by the liquid-gas curve in the phase diagram for water ( Figure 10.31 ), and a two-phase equilibrium of liquid and gaseous phases remains. At a temperature of 374 °C, the vapor pressure has risen to 218 atm, and any further increase in temperature results.

The phase diagram for water is shown in the Figure below . Figure 13.26. Phase diagram for water. Notice one key difference between the general phase diagram and the phase diagram for water. In water's diagram, the slope of the line between the solid and liquid states is negative rather than positive. The reason is that water is an unusual.

We can use the phase diagram to identify the physical state of a sample of water under specified conditions of pressure and temperature. For example, a pressure of 50 kPa and a temperature of −10 °C correspond to the region of the diagram labeled "ice.". Under these conditions, water exists only as a solid (ice).

In the video here, Sal uses a horizontal line through the phase diagram. But, it doesn't have to be horizontal. Imagine a vertical line through this diagram-- for water, choose 100 degrees C. As long as you are at 100 C, you can change the phase by changing the pressure on the system.

Crystalline solids can have multiple possible structures, dependent on thermodynamic variables. This is why you may hear someone talk about different forms of ice, such as ice II, ice.

Consider the phase diagram for carbon dioxide shown in Figure \(\PageIndex{5}\) as another example. The solid-liquid curve exhibits a positive slope, indicating that the melting point for CO 2 increases with pressure as it does for most substances (water being a notable exception as described previously). Notice that the triple point is well above 1 atm, indicating that carbon dioxide cannot.
