Is Water Flammable?

The reason that water (in any state) is not flammable is that it is already the product of combustion. The chemical equation for this reaction is: 2H₂ + O₂ -> 2H₂O. The reaction also releases a large amount of energy, mostly in the form of heat that causes the water vapor to expand rapidly to a large volume.

Is water ever flammable?

Water is not flammable and can't catch on fire. This is because it is made of hydrogen, which has been fully oxidized and can't react with oxygen any further. However, the hydrogen and oxygen can fuel and increase a fire when they are separated.

At what temperature is water flammable?

Any liquid with a flashpoint between 100°F - 200°F is considered combustible.
