Gas is known as the state of aggregation of matter that has no shape or volume own self. It is mainly composed of unbound, expanded molecules with little force from attraction with each other which is what makes them not have a defined shape and volume, what will happen is that it will expand and occupy the entire volume of the container that contains it.

Although gas is generally used as a synonym for steam, this only occurs with gas that can be condensed or pressurized if subjected to a temperature constant.
Unlike solids that have a well-defined and difficult-to-compress shape and flowing and flowing liquids, gases they expand freely as we said above and their density it is much less than that of liquids and solids.

A type of gas that is well known and used by most of the human beings that inhabit this planet earth when cooking is called natural gasresulting from the mixture of gases that are generally found in fossil deposits and although it can vary from deposit to deposit, generally, It is composed of methane in an amount that does not exceed 90 or 95% and the rest is a sum of other gases such as nitrogen, ethane, butane, among others.

The gas It can also be obtained through the remains of decomposition processes of organic remains such as garbage, vegetables and swamp gases and is called biogas.
