Water is a clear, odorless, and tasteless liquid that occurs naturally on Earth. It is essential for all forms of life and has various important properties. Water is composed of two hydrogen atoms bonded to one oxygen atom, resulting in its chemical formula H2O. It exists in three states: solid (ice), liquid (water), and gas (water vapor). Water covers around 71% of Earth's surface and plays a crucial role in the water cycle, which involves evaporation, condensation, and precipitation. It is used for drinking, cooking, agriculture, transportation, energy production, and recreational activities, among many other purposes.
