Water (chemical formula H2O) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth‘s hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. “Water” is the name of the liquid state of H2O at standard conditions for temperature and pressure.
Water vapor, often known as water vapour or aqueous vapor, is the gaseous phase of water. It is a kind of water in the hydrosphere. Water vapor can be formed through the evaporation or boiling of liquid water, or by the sublimation of ice. Water vapor, like the majority of the atmosphere’s elements, is transparent. Water vapor is continually produced by evaporation and eliminated by condensation under normal atmospheric conditions. It is less dense than most other air components and causes convection currents, which can lead to clouds.
