  2. Reid vapor pressure - Wikipedia

    en.wikipedia.org/wiki/Reid_vapor_pressure

    Reid vapor pressure (RVP) is a common measure of the volatility of gasoline and other petroleum products. [1] It is defined as the absolute vapor pressure exerted by the vapor of the liquid and any dissolved gases/moisture at 37.8 °C (100 °F) as determined by the test method ASTM-D-323, which was first developed in 1930 [2] and has been revised several times (the latest version is ASTM D323 ...

  3. Volatility (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Volatility_(chemistry)

    Bromine liquid readily transitions to vapor at room temperature, indicating high volatility. In chemistry , volatility is a material quality which describes how readily a substance vaporizes . At a given temperature and pressure , a substance with high volatility is more likely to exist as a vapour , while a substance with low volatility is ...

  4. Vapor pressure - Wikipedia

    en.wikipedia.org/wiki/Vapor_pressure

    With any incremental increase in that temperature, the vapor pressure becomes sufficient to overcome atmospheric pressure and cause the liquid to form vapor bubbles. Bubble formation in greater depths of liquid requires a slightly higher temperature due to the higher fluid pressure, due to hydrostatic pressure of the fluid mass above. More ...

  7. Combustibility and flammability - Wikipedia

    en.wikipedia.org/wiki/Combustibility_and...

    The degree of flammability in air depends largely upon the volatility of the material – this is related to its composition-specific vapour pressure, which is temperature dependent. The quantity of vapour produced can be enhanced by increasing the surface area of the material forming a mist or dust. Take wood as an example.

  8. True vapor pressure - Wikipedia

    en.wikipedia.org/wiki/True_vapor_pressure

    True vapor pressure (TVP) is a common measure of the volatility of petroleum distillate fuels. It is defined as the equilibrium partial pressure exerted by a volatile organic liquid as a function of temperature as determined by the test method ASTM D 2879.
