- The term “water” refers to a transparent, odorless, and tasteless liquid that is essential for all known forms of life.
Water molecules consist of two hydrogen atoms and one oxygen atom, bonded together by covalent bonds.
Its molecular formula is H2O. Being a polar molecule, water exhibits various unique properties such as high heat capacity,
universal solvent abilities, and surface tension.
Water plays a vital role in maintaining the Earth’s ecosystem. It exists in different forms, including lakes, rivers, oceans, and glaciers.
Not only is water essential for hydration and basic bodily functions, but it also serves as a medium for transportation, regulates climate,
sustains agriculture, and supports aquatic life.
- Water undergoes the hydrological cycle, where it constantly moves between the atmosphere, land, and oceans through processes like evaporation,
condensation, precipitation, and runoff. This cycle ensures the distribution of water across the planet and helps to maintain ecological balance.
