Vapor pressure formulation for ice

open access: yesJournal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1977
A new formulation is presented for the vapor pressure of ice from the triple point to −100 °C based on thermodynamic calculations. Use is made of the definitive experimental value of the vapor pressure of water at its triple point recently obtained by Guildner, Johnson, and Jones. A table is given of the vapor pressure as a function of temperature at 0.

Variation of Relative Humidity as Seen through Linking Water Vapor to Air Temperature: An Assessment of Interannual Variations in the Near-Surface Atmosphere

open access: yesAtmosphere, 2022
It has generally been regarded that, in the warming climate, atmospheric water vapor may increase due to the enhancement in surface evaporation, which is expected from the Clausius–Clapeyron (C–C) equation, along with the assumption that relative ...

New convenient vapor pressure-temperature correlation for some aliphatic hydrocarbons

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2013
New empirical equations for correlating temperature dependence of vapor pressure for C6-C20 aliphatic hydrocarbons are proposed: ln(VP) = k1·T/(k2+T) where, VP – vapor pressure, T – temperature, k1 – asymptotic maximum vapor pressure, and k2 ...
