Vapor Pressure Data: Hydrogen
24 to 28.5
Tabulated vapor pressure vs temperature for ~2800 pure compounds (inorganic and organic). Each row gives vapor pressure in Pa at a specific temperature in Kelvin. Covers cryogenic to high-boiling-point ranges. Includes water (ice, supercooled, and liquid phases), gases, organics, metals, and inorganic salts.
