@moorkh
you are saying
heat absorbed during the process of breaking water molecule = heat released when a molecule of hydrogen is burnt
are you sure ?
let me put it this way.
water = 2x Hydrogen atoms and 1x Oxygen atom
hydrogen molecule = 2x hydrogen atom
oxygen molecule = 2x oxygen atom
when we burn hydrogen to create water
2x hydrogen molecule + 1x oxygen molecule --> 2x water molecule + energy1
when we conduct electrolysis of water
2x water molecule + energy2 ---> 2x hydrogen molecule + 1x oxygen molecule
energy1 = energy2
