The word gas was coined by the scientist Jan Baptista van Helmont in the first half of XVII century , from the Latin word bye. It's about that matter that has low density and that, therefore, can extend indefinitely.

This allows us to say that gas is the State of aggregation of a matter that lacks volume and its own form, something that allows it to differentiate itself from a liquid or of a solid .

When talking about gas we have to determine that several are the hallmarks that clearly identify them with respect to other types of fluid. Thus, among them is the fact that there is a large vacuum distance between the particles that make it up, which brings with it that its understanding is possible.

In the same way it is also established that the said particles are at all times in motion which means that they are hitting the walls of the containers that contain them on which they exert pressure.

And all this without forgetting the fact that when two gases come into contact, what is produced is a mixture in which particles of both are perfectly and evenly distributed. This is achieved both to the aforementioned movement that they have at all times and to the large space that exists between them.

The term is used, generically, to refer to gases capable of generating combustion and that are used in the home or the industry . For example: "Beware of that stove that has little gas and does not cook well", "We have to pay the gas or they will cut it and we will have to take a shower with cold water", "A gas leak caused the explosion".

Gas, on the other hand, is the combination between air and a fuel product that serves to put into operation a engine : “I have to load gas to the car so we can get to the beach without problem”, "I want to buy a car that works on gas because it is cheaper than gasoline".

Thanks to its capacity as a fuel, the notion of gas is used, figuratively, as a synonym for impulse , force or start : “This team must be given gas, it cannot be that he loses three straight games at home”, "I need gas, I can't stand another night awake because of the study".

Currently we can establish that we find a great variety of gases. Thus, for example, there is talk of what is called gas city, which is the one that is distributed through urban networks to ensure that in each household there is the necessary fuel to carry out actions such as cooking or enjoying hot water.

In the same way, there is the hilarious gas that is defined because it has a series of characteristics or properties of anesthetic type.

This term, in addition to everything cited, is used in a series of popular expressions such as “full throttle” with which it is said that a person or a vehicle is running at high speed.

It should be noted, finally, that all gases that are generated in the gas are known as gas digestive system . The flatulence They are the gaseous mixtures expelled through the anus that have a very particular sound and smell.
