English: Log-lin chart of vapor pressure vs temperature for various liquids based on File:Vapor_Pressure_Chart.png. Date: 5 October 2007: Source: ... You are free: to ...
Although the relation between vapor pressure and temperature is non-linear, the chart uses a logarithmic vertical axis to produce slightly curved lines, so one chart can graph many liquids. A nearly straight line is obtained when the logarithm of the vapor pressure is plotted against 1/(T + 230) [8] where T is the temperature in degrees Celsius ...
Values are given in terms of temperature necessary to reach the specified pressure. Valid results within the quoted ranges from most equations are included in the table for comparison. A conversion factor is included into the original first coefficients of the equations to provide the pressure in pascals (CR2: 5.006, SMI: -0.875).
English: Plot of water vapor pressure p in Torr (mmHg) and hPa versus Temperature T in degrees Celsius. Note that the vapor pressure equals atmospheric pressure (760 Torr) at the boiling temperature of water. Produced by Yannick Trottier in 2006.

The boiling point of water is the temperature at which the saturated vapor pressure equals the ambient pressure. Water supercooled below its normal freezing point has a higher vapor pressure than that of ice at the same temperature and is, thus, unstable. Calculations of the (saturation) vapor pressure of water are commonly used in meteorology.
Isopropanol vapor pressure (logarithmic scale) vs temperature. Drawn using data published in [2] [3] Distillation data. Vapor-liquid equilibrium for isopropanol/water [4]
The path or series of states through which a system passes from an initial equilibrium state to a final equilibrium state [1] and can be viewed graphically on a pressure-volume (P-V), pressure-temperature (P-T), and temperature-entropy (T-s) diagrams. [2] There are an infinite number of possible paths from an initial point to an end point in a ...
