I didn't pay much attention during chem class but it seems that you
must have cut class when this was disscussed. You may have noticed
some sweating on your pans if you put a pan filled with a cool liquid
on the stove or maybe you've seen some condensation near the vent of
your oven while preheating. Guess where the water is coming from.
Burning PLG or LNG will produce a large amount of water. Don't take my
word for it. Google it! :-)
