Water, water, water - H2O - Uriyadi Thiruvizha

Water  is vital for all known forms of life, despite not providing food, energy or organic micronutrients. A number of natural states of water exist.  Water, is a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states. It is one of the most plentiful and essential of compounds.  

Can you see water ?  - no,  not as in buckets, rivers, Ocean or elsewhere – the Q is how many drops make an Ocean and can you see them individually ? Water (chemical formula H2O) is an inorganic, transparent, tasteless, odorless, and nearly colourless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms.  "Water" is the name of the liquid state of H2O at standard temperature and pressure.  


This is an age where not many of the residents of the city depend on Chennai Metro water – for some – it is ‘branded mineral water’ ! or packaged water. 


Water has an amazing ability to adhere (stick) to itself and to other substances. The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a "sticky" liquid.  

Hydrogen bonds are attractions of electrostatic force caused by the difference in charge between slightly positive hydrogen ions and other, slightly negative ions. In the case of water, hydrogen bonds form between neighbouring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond. 

Electrolysis of water is the decomposition of water (H2O) into oxygen (O2) and hydrogen (H2) due to an electric current being passed through the water. 

To find out what water is made of, it helps to look at its chemical formula, which is H2O. This basically tells us that the water molecule is composed of two elements: hydrogen and oxygen or, more precisely, two hydrogen atoms (H2) and one oxygen atom (O). Hydrogen and oxygen are gases at room temperature. So, does this mean that we can just combine both gases and then we get water? It is not quite as simple as that. What is missing in the equation is the energy component of the chemical reaction. Making water from its elements produces a large amount of energy. Chemical reactions that produce energy are also called exothermic reactions. In the case of hydrogen and oxygen the released energy is so high that it is almost impossible to control, and most of the time it leads to an explosion.   

To create water, oxygen and hydrogen atoms must be present. Mixing them together doesn't help; you're still left with just separate hydrogen and oxygen atoms. The orbits of each atom's electrons must become linked, and to do that we must have a sudden burst of energy to get these shy things to hook up.  The ill-fated blimp, the Hindenburg, was filled with hydrogen to keep it afloat. As it approached New Jersey May 6, 1937, to land after a trans-Atlantic voyage, static electricity (or an act of sabotage, according to some) caused the hydrogen to spark. When mixed with the ambient oxygen in the air, the hydrogen exploded, enveloping the Hindenburg in a ball of fire that completely destroyed the ship within half a minute. There was, however, also a lot of water created by this explosion. 

To create enough drinking water to sustain the global population, a very dangerous and incredibly large-scale process would be required. 

Not intended to be any Scientific post – just to put up some photos of water splash experienced and enjoyed during Uriyadi Uthsavam conducted every year, celebrating the birth of Sree Krishna Bagwan.


Here are some photos of Uriyadi in front of Thiruvallikkeni Sri Parthasarathi Emperuman thirukovil in 2022
