As a subject matter expert in chemistry and physics, I can provide an explanation for the concept of "burning water."

Water, in its liquid form, is not combustible because it does not contain the necessary fuel to support combustion. However, under certain conditions, water can be involved in a chemical reaction that releases energy, which might be colloquially referred to as "burning." For example, when water is electrolyzed, it can be split into its constituent elements, hydrogen and oxygen. Hydrogen is a highly flammable gas and can be ignited, causing it to burn. This process does not burn the water itself but rather a byproduct of a chemical reaction involving water.

Water is made up of two elements, hydrogen and oxygen. Hydrogen is flammable, but oxygen is not. ... You can't burn pure water, which is why we use it to put out fires instead of starting them. You can, however, break it down into hydrogen and oxygen by putting energy into it, in the form of an electric current.read more >>
