water, air, and fire

The chemical composition of water is H2O – two hydrogen atoms and one oxygen atom. The properties of water are special because of the way its atoms bond together to form a water molecule, and the way the molecules interact with each other.

Air is mostly gas.

It's a mixture of different gases. The air in Earth's atmosphere is made up of approximately 78% nitrogen and 21% oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.

Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire.
