i am not a pro, moar of a physics cs fag
CRC handbook of chemistry and physics (1969):
the vapor pressure is given for organic and inorganic compounds, in two tables
less than or greater than one atmosphere
at the very end of pages of the greater thanz, nitric acid gets its own exclusive breakout table
the closest thing i found quick was the pic attached.
excerpt from Sorospedia:
Vapor pressure (or vapour pressure in British English; see spelling differences) or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The equilibrium vapor pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapor pressure at normal temperatures is often referred to as volatile. The pressure exhibited by vapor present above a liquid surface is known as vapor pressure. As the temperature of a liquid increases, the kinetic energy of its molecules also increases. As the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure.
The vapor pressure of any substance increases non-linearly with temperature according to the Clausius–Clapeyron relation. The atmospheric pressure boiling point of a liquid (also known as the normal boiling point) is the temperature at which the vapor pressure equals the ambient atmospheric pressure. With any incremental increase in that temperature, the vapor pressure becomes sufficient to overcome atmospheric pressure and lift the liquid to form vapor bubbles inside the bulk of the substance. Bubble formation deeper in the liquid requires a higher temperature due to the higher fluid pressure, because fluid pressure increases above the atmospheric pressure as the depth increases. More important at shallow depths is the higher temperature required to start bubble formation. The surface tension of the bubble wall leads to an overpressure in the very small, initial bubbles.

chemanon yesterday posted a pic of a nitric acid fire in Germany iirc, with the same characteristic ~~red~~ brown smoke.
i am unsure of the combustion process for ammonium nitrate, it was suggested nitric acid could result, i do not know. i do not remember if there was red smoke at the Oklahoma bombing involving ammonium nitrate.
it appears to be present in Beirut, and would seem to be a significant accelerant.
thanks for asking.
