Gaseous. A state of aggregation of matter characterized by leaving the substance without its own format or volume. Its main composition is unbound molecules, expanded and with little attractive force, causing them to have no volume and defined shape, causing it to expand to occupy the entire volume of the container that contains it.

Origin
The word gaseous is part of the group of adjectives and is used to identify all substances that are in the form of gas or the liquid that emanates, possesses or generates gases. When the term is written in feminine (soda), it is used specifically to refer to an effervescent drink devoid of alcohol that is usually enjoyed as a soft drink.
- State that is characteristic of gas. – A substance in a gaseous state
- It is in a gas state. – gaseous substance
Manual Dictionary of the Spanish Language

characteristics
The main characteristic of matter in the gaseous state is that its molecules exert a very low power of attraction to each other, moving at high speed and being distanced, which is why the molecules are distributed throughout the space in which they are keep it contained. Gas molecules are identified because they are in what is known as a state of chaos, in disorder.
- The gravitationaland attractive forces between particles are negligible.
- There is practically no cohesion.
- Its density is much less than that of liquids and solids.
- Dynamicand free movement of molecules
- Molecules move so fast that they free each other.
- They occupy a much larger volumethan in the other states because their molecules leave intermediate free spaces and are enormously separated from each other.
- Expands to completely fill any container.
- Variable volumedepending on the container container.
- Does not observe a definite shape
- The compressionis simple, which means, in this case, decrease the distance between molecules.
The gaseous state of matter
The gaseous state of matter is a form of matter in which its particles are in a high state of energy , causing them to vibrate rapidly, experience strong repulsion from each other, and tend to separate as much as possible with high-speed vector displacement in random directions. The gaseous state is recognized as a state of matter between the liquid state (lower energy levels ) and the plasma(higher energy levels). Because the particles of a gas are widely separated from each other, they will have weaker intermolecular bonds than liquids and solids. The gaseous state, along with plasma, is the most abundant state in the universe , with some traces of solid matter , due to the fact that the vast majority of them are predominantly hydrogen and helium .
Importance of the gaseous state
The fascination of this state is that we can experiment with it without seeing it, since most of it is colorless . The investigations on gases were fundamental in the knowledge of the intense structure of matter.
- Lavoisier: French scientist to discover the law of conservation of mass , studied the reaction between hydrogen and oxygen in the gas phase to synthesize water.
- As a result of understanding the properties of gases, the properties of solids and liquids could be explained.
In the development of atomic theory
- Dalton, English scientist who raised the idea of the indivisible atom to explain the laws of chemical combination and the empirical laws of gases .
- Gay Lussacand Avogadro , studying the behavior of gases, discovered the gas combination law and introduced the concept of the molecule.
- The electronsand protons were discovered as cathode ray and canal rays respectively, when scientists investigating the electrical conductivity in gases within a tube to the vacuum .
- Many atomic and molecular properties have been found in the gas phase, such as ionization energyand electronic affinity .
Gas particles
The particles that make up matter can appear in three different physical states, mainly, solid, liquid and gaseous. The difference between the three lies essentially in the agitation of the molecules, which is the expression of their thermal condition . The particles of the gases will change their direction by the action of gravity , when interacting with other particles, or with electromagnetic fields , or another form of external energy.
Electromagnetically charged particles of gas with the same polarity repel each other, while charged particles of opposite polarity attract each other.
When the particles of a gas lose energy in the form of heat, they will condense or liquefy, transforming them into liquids. If the particles of a gas increase their energy level, therefore their vibration, they will lose their electrons and go into the state of matter called plasma.
The gaseous state particles are practically free and have a high energy level, enough to conserve their electrons and possibly make interactions with other particles, generally to react or slide through them, for which gases are said to flow from areas with higher pressure towards lower pressure areas.
The behavior of gases varies according to the structure of the nucleus, its particles, its symmetry , its size, its atomic mass , the amount of kinetic energy in its particles, the characteristics of its electromagnetic charge and its electrostatic field , as well as its electromagnetic bonds with other particles (in case of compounds).
