Eli5 – how can water be made of hydrogen and oxygen?

517 views

Liquid water – made from two types of gas. Makes no sense to me, whatsoever. Water seems to be one of the strangest substances and we completely take it for granted that, apparently, it’s made of gas!

Gas is just a state of matter. If you cool oxygen or hydrogen enough, you get liquid oxygen and liquid hydrogen. If you heat steel you get liquid steel. You can even vaporise it if you get it really hot.

Remember you have the three basic states, solid, liquid and gas. To make something go from a solid to a gas requires adding energy (heating) and to go the other way you remove energy (cooling).

Everything is made of atoms and the amount of energy those atoms have decides what state it is. Oxygen and hydrogen alone need far less energy than water to be a gas, but combine them and they suddenly need a lot more energy. Give water enough energy and it turns to steam, which is also a gas.

So water being made of hydrogen and oxygen is no more unusual than wood being made of carbon and other atoms.

Water can also be a gas, (water Vapor) and a solid (ice) the state of it all depends on how “hot” matter is, if you cool down oxygen real low it will become a liquid aswell. It just so happens to be, water is a liquid between 0-100 degrees Celsius

Also oxygen and hydrogen aren’t a gas, they are molecules which happen to be in a gas form at room temperature

edit: i made a mistake.

Wait until you find out that there is no difference between solid, liquid and gas except the density.
