ELi5: How water puts out fire if the two components, hydrogen and oxygen, are both highly flammable

476 views

If the two are both highly reactive and easily flammable (like the Hindenburg disaster for example), how do they put out flames? Same question with Sodium and Chlorine, one being highly explosive when it touches water and the other being a deadly gas, but combined they make tasty rocks.

Water is the waste product of burning hydrogen and oxygen.

When they are burned, they create a bond and in the process a lot of heat is released. The result of them bonding, is water.

In order to break that bond, the same amount of energy that was released during the burning process, would have to be put back in.

However, long before a temperature is reached that could break this bond, the water will boil away and by boiling away it takes heat away from the fire.

And before it boils away it creates a film over the flammable material and keeps it separated from the oxygen in the air, that is needed in order to burn.
