These collisions are perfectly elastic, meaning that all of the kinetic energy from the collision is transferred to the next molecule, not converted into heat or friction. This means that, over time, the gas will n ...

Electrolysis of water
Electrolysis of water is the decomposition of water (H2O) into oxygen (O2) and hydrogen gas (H2) due to an electric current being passed through the water.This technique can be used to make hydrogen fuel (hydrogen gas) and breathable oxygen; though currently most industrial methods make hydrogen fuel from natural gas instead.
