A typical mid-grade gasoline
from US Oil and Refining Co has a flash point
of -43°C; all gasolines and similar hydrocarbon liquids will have flash points
below the freezing point of water. This means that at ANY reasonable ambient
temperature, there are dangerous quantities of fumes above any substantial
amount of gasoline. The boiling point is a bit problematic; the
gasolines cited above lists 9 or 10 ingredients, many of which are
themselves mixtures, and many of which have rather different boiling points. And
different gasolines, even from the same company, will have different
ingredients,allegedly fine-tuned to meet the octane rating and the local air
quality standards. (stolen from one of ask jeeves's expert's answer, just can't
remember who.)
