Gas is known as the state of aggregation of matter that does not have its own shape or volume. Mainly it is composed of unbound, expanded molecules with little force of attraction to 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 happens with gas that can condense or become pressurized if it is subjected to a constant temperature.
Unlike solids that have a well-defined and difficult to compress shape and fluids that flow and flow, gases expand freely as we mentioned above and their density is much lower 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 gas. that results 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 organic waste decomposition processes such as garbage, vegetables and swamp gases and is called biogas.
Obviously These types must be processed for the domestic or commercial use mentioned.
