There was an important word from science in that explanation, did you catch it? A physical change is characterized by a metamorphosis occurring in which matter retains its molecular structure. Generally, these reactions are not reversible except by another chemical reaction. It’s important to note that the water’s molecular structure, or chemical identity, is still the same, two hydrogen molecules and one oxygen molecule, regardless of its physical state. For combustion to occur, you need to combine three substances: fuel, oxygen, and heat, with fuel being wood, gas, or oil.
