Water (the chemical compound)

Water is a chemical compound made up of two hydrogen atoms bonded to one oxygen atom, forming H₂O. It is a vital substance for all known forms of life, acting as a solvent that dissolves many substances, enabling biological processes. Water can exist in three states: liquid, solid (ice), and gas (vapor). It has unique properties like high specific heat, which helps regulate temperature, and surface tension, which allows it to form droplets. Its versatility makes it essential for drinking, agriculture, industry, and maintaining ecosystems worldwide.
