If hydrogen and oxygen are both gases, where does the liquid in water come from? - H2 - O2 - H20 - Ask Scarlett

Ranger Rick, July, 1997

It's all a matter of chemistry. Even though a water molecule is made up of two hydrogen atoms and one oxygen atom, it's very different from molecules of either hydrogen or oxygen. When molecules combine, they form new and different molecules. Look at it this way: A waffle isn't anything like the milk, oil, and flour that went into it, right?
