Water is one of the most essential substances on Earth, sustaining life and supporting ecosystems. Chemically, water is composed of two hydrogen atoms and one oxygen atom, giving it the scientific name Dihydrogen Monoxide (H₂O). This article explores the properties, significance, and various uses of water while delving into its scientific aspects.
Scientific Classification of Water

Fun Facts About Water
- About 71% of Earth’s surface is covered with water.
- Only 2.5% of Earth’s water is freshwater, and less than 1% is accessible for human use.
- A single drop of water can contain millions of microorganisms.
- Water expands when it freezes, which is why ice floats.
- Hot water freezes faster than cold water under certain conditions (Mpemba Effect).
