a P-T condition where liquid is the thermodynamically stable phase for the compound. You need liquid to evaporate, and you cannot have liquid outside the range of stability. Of course, you also need a vapor pressure in the contact gas phase which is less than the maximum possible vapor pressure for that condition, but first, to have any evaporation, you must have some liquid. then the question becomes one of whether the vapor phase in contact is saturated or not with respect to water vapor.
One could dump liquid water at earth surface pressure into a blast furnace and the water will rapidly convert completely to steam (vapor), but the liquid water will not rise above the boiling temperature in the process, because it cannot be above boiling temp and remain liquid. That is, even if the system temp is far above boiling temp, the water will take time to get to that temp. The time can be extremely short, is all.
