As I understand it, liquid gasoline itself won't explode,
but the vapor can.
IIRC any thing that burns has to be a vapor first.
vapor/gas
So solid nitro powder wont' burn unless it is
fist evaporated?
I'm no chemist but that is how I understand it. Some how the dry
chemical will turn to a liquid then a gas before it will burn.
That is what we were taught in chemistry class.
And understand that the whole thing does not have to turn into a liquid,
only the portion next to the heat source so that it can evaporate and
provide fuel to the flame.
IIRC a candle was used to demonstrate the stages of the process.
Some elements/mistures change forms very quickly.
