im not sure if this is the appropriate forum for this question, but its seems a bit to acedemic for any of the others.
on thermodynamic data charts (e.g. H,G,S) they usually say the data for gases is at 1atm and 25C, but for some substances its vapor phase cannot occur at 1atm and 25C, because it would condense (e.g. water vapor).
in these cases should one presume the data is taken at the minumum temperature at which a vapor pressure of 1atm could exist?
for example 100C for water
