Look up the definition of "flash point". It is not intuitive and
not what a lot of people think of or invision, and is not related to boiling
point. For instance, gasoline has a flashpoint of something like 60
belowF. The gas in my car is something like 160 degrees ABOVE its
flashpoint and it hasn't blown up yet!
