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.

A candle needs atmospheric oxygen. Nitro powder
doesn't.

Understood but does the nitro not create oxygen during the
transformation process?

It releases it, it doesn't consume it.

Then there's nitro itself, which goes boom
in
liquid bulk.
