in case it is a surprise to you, gasoline burns. But WATER puts it out.

Nope.  Gasoline floats on water.  The specific gravity of gasoline is
about 0.75.  Specific gravity of water is defined as 1.0.  Gasoline is
not immiscible with water (i.e. does not create a homogenous fluid
when mixed).  Try to recall an action movie where various forms of
gasoline and diesel fuel are burning on the surface of the ocean,
while the hero swims UNDER the burning gasoline to rescue someone.

What does happen is that the water cools whatever is burning which
eventually puts out the fire.  At 25C, it takes about 5 times as much
energy to vaporize water as it does gasoline.  The burning gasoline
will vaporize some water, but in the process cools both the gasoline
and the water down considerably.  Eventually, the temperature becomes
low enough that the gasoline stops turning into a vapor and the fire
goes out.  It's the vapor that's burning, not the liquid.
