This molecule is fundamental to life, acting as a solvent, temperature regulator, and participant in biological reactions. Water covers about 71% of Earth’s surface and exists in three states—solid (ice), liquid, and gas (vapor). It is vital for metabolism, transportation of nutrients, and maintaining ecological balance. The strong hydrogen bonds between its molecules give water unique properties like high surface tension and specific heat capacity.
