water - the most important resource in the world
H2O - chemical connection of hydrogen with oxygen
boiling temperature: 100 C° - freezing point: 0 C° - greater density (1g/cm3): 4 C°
Why using rain water?
There are many answers to this question. Some very good answers we offer you below!
Pure water has a low electrical conductivity, which increases with the dissolution of a small amount of ionic material such as common salt.
Liquid water can be split into the elements hydrogen and oxygen by passing an electric current through it - a process called electrolysis. The decomposition requires more energy input than the heat released by the inverse process (285.8 kJ/mol, or 15.9 MJ/kg).
