What Is The Relationship Between Water And Energy?

What happens to water when electricity passes through it?

When an electric current is passed through water, “Electrolysis of water” occurs, which is the decomposition of water (H2O) into hydrogen gas (H2) and oxygen (O2).

Hydrogen gas forms at the cathode where the electrons enter the water and at the anode, oxygen is formed..

Does water give energy?
