Even though water contains elements known to burn, its molecules have a unique specific heat capacity that keeps it from burning. Once it reaches that capacity, it will start to boil. If it goes higher than that capacity, then it will evaporate.
For a substance to burn, it must be combustible.On the other hand, water not only being incombustible but it is a substance that extinguishes fire. So, it does not burn.
A2. But most importantly, water is made by burning Hydrogen, so it has already been burnt.
Because water has hydrogen that has already been "burned".
The energy in the bonds of 2 water molecules (H20) are lower than the bonds
of 2 molecules of hydrogen (H2) and one molecule of oxygen (O2). So when
you bring H2 and O2 together with a tiny bit of energy (a flame or spark
just to start it), it will burn, releasing energy, and making water.
You can make hydrogen and oxygen from water by electrolysis, but that uses
energy, sort of like the reverse of burning.
The burning of gasoline is very similar, the bonds start off with more
energy, which is released on burning with oxygen to make CO2 (carbon
dioxide) and water. However, making gasoline from CO2 and water is
extremely difficult although with enough energy it's theoretically possible.

There is no simple way to explain. I was going to say that it could be due to lack of carbon, but that'd be incorrect as if you ground many solids into very fine particles you can make them fire up, with a source flame of course
^ that is a very good answer^ I'm going to try and write it simply... here goes.
Water does not burn because when something is burning it combines with oxygen and since the hydrogen has already been combined with oxygen it cannot burn. It is also very stable. I'm pretty sure this is right
water doesn't burn because it is water you silly little truffle! lol... sorry i was just bored.
The only good answer I ever got was. Anything that is already burned wont burn. Nobody knows
Actually, it can.
Water can extinguish fires except there are many things that can catch on fire like for example electronics or chemicals etc. so they are different types of fires and each fire has its own fire extinguishers that can put them out easily.
it doesn't burn because the water keeps the cup...like,.....cold so it doesn't burn.. the water does evaporate, but as long as the water's there the cup doesn't burn.
Oxygen is an oxidizer that will assist in the combustion of something else, however, oxygen itself will not burn because it is not flammable.
Water is totally oxidized hydrogen. It is essentially hydrogen "ash". Just as yo cannot reignite the ashes from a fire you cannot reburn hydrogen after it is water.
because the water extinguishes the fire.
Because it is paper
It does not burn because it is putting it out basically.
the paper cup cannot become appreciably hotter than the water it contains
Plastic is an insulator. but most of the paper is not insulated, because the paper in general contains water, although the content is very low, but enough to pass current, but there also is a special insulation paper, that is on the special purpose. so in dry conditions, and the cup has no water, a plastic cup is a better insulator than a paper cup.

NO
The boiling point of water is 100 degrees. However, the point at which paper burns is much higher than 100 degrees. When you boil water in a paper cup, all of the heat is transferred to the water, not the cup. When the water starts to boil, the paper stays unburnt. After the water has boiled through, there should be a small black mark on the base of the cup which can be easily removed.
no
-- Take a measuring cup and a paper cup. -- Using the measuring cup, pour about 3.7 fluid ounces of water into the paper cup. -- The weight of the paper cup in your hand is now about 1 newton.
the plastic bag filled with water doesn't catch on fire, because the water in the bag will absorb the heat energy from the fire and when the plastic melts it will dump the water on the source of fire and out it

The wet dollar bill is saturated with water. Water does not burn, so the paper dollar bill can't burn until the water has evaporated.
we would the cup and the paper burn like when you put news paper on a bbq.
