Expert Answer:

Water is a compound of hydrogen and oxygen which contains the two elements chemically combined in a fixed proportion by mass.

Because it is a compound, its properties are very different from that of the combining elements (hydrogen and oxygen).

Water cools the combustible material so that its temperature is brought below its ignition temperature. This prevents the fire from spreading.

Water vapours also surround the combustible material, helping in cutting off the supply of air. So, the fire is extinguished.
