Question

Is water a fuel ?

Answer 1

Dear Student

Fuels are sources of "free energy", F The amount of F above the minimum in some environment is the amount of energy available to do large-scale work. A fuel like petrol can release lots of energy when it reacts with oxygen in the atmosphere. So petrol in an O₂ atmosphere has lots of extra F. Water doesn't have any. The reason is very simple. Water is hydrogen that already has been burned. So it's not a fuel anymore.

Hope this helps you
