Gas is one of the three forms of matter. Every known substance is either a solid, liquid or a gas. These forms differ in the way they fill space and change shape. A gas, such as air has neither a fixed shape nor a fixed volume and has weight.
The reactions of matter whether occurring in natural processes or in the laboratories can be interpreted using another language of chemistry – the equation. A chemical reaction transforms one or more substances into a set of different substances. The substances that enter into a chemical reaction are called reactants and the substances formed are the products.
