Phase Diagrams of Water 101 Diagrams
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.

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.

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 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.
Phase Diagram of Water (H2O)
Simplified temperature/pressure phase change diagram for water. The pressure on a pressure-temperature diagram (such as the water phase diagram shown above) is the partial pressure of the substance in question.. A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions (pressure, temperature, volume, etc.) at which.
Phase Diagrams CK12 Foundation
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.

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).

An Efficient Way to Predict Water's Phases. A machine-learning technique maps water's phase space as reliably as gold standard ab initio calculations but at a much smaller computational cost. Given its familiarity, water is a surprisingly tricky substance to simulate. In addition to having liquid and gas phases, water adopts at least 14.

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.

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.

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.

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.
