  2. Vapor pressure - Wikipedia

    en.wikipedia.org/wiki/Vapor_pressure

    A log-lin vapor pressure chart for various liquids. As a general trend, vapor pressures of liquids at ambient temperatures increase with decreasing boiling points. This is illustrated in the vapor pressure chart (see right) that shows graphs of the vapor pressures versus temperatures for a variety of liquids. [7]

  3. Vapor pressures of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Vapor_pressures_of_the...

    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).

  4. International Standard Atmosphere - Wikipedia

    Comparison of a graph of International Standard Atmosphere temperature and pressure and approximate altitudes of various objects and successful stratospheric jumps The International Standard Atmosphere ( ISA ) is a static atmospheric model of how the pressure , temperature , density , and viscosity of the Earth's atmosphere change over a wide ...

  5. Thermodynamic diagrams - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_diagrams

    The main feature of thermodynamic diagrams is the equivalence between the area in the diagram and energy. When air changes pressure and temperature during a process and prescribes a closed curve within the diagram the area enclosed by this curve is proportional to the energy which has been gained or released by the air.

  6. Orders of magnitude (pressure) - Wikipedia

    The chart analysis today shows that caution and patience would remain the best action. Today we are analyzing the SPDR S&P 500 (NYSEMKT: S&P Chart Warning as Industry Leaders Add Pressure

  8. Antoine equation - Wikipedia

    en.wikipedia.org/wiki/Antoine_equation

    The Antoine equation is ⁡ = +. where p is the vapor pressure, T is temperature (in °C or in K according to the value of C) and A, B and C are component-specific constants.. The simplified form with C set to zero:

  9. Station model - Wikipedia

    en.wikipedia.org/wiki/Station_model

    On the top right corner of the model for a surface weather map is the pressure, showing the last two integer digits of the pressure in millibars, or hectopascals, along with the first decimal. For instance, if the pressure at a certain location is 999.7 hPa, the pressure portion of the station model will read 997.
