What are the characteristics of gaseous substances?
Gases (substances that exist in the gaseous state) do not have any definite shapes and do not occupy fixed volumes. Gaseous substances occupy the shape of their container and are highly compressible. Gases have a lower density and are highly compressible as compared to solids and liquids. They exert an equal amount of pressure in all directions.

Common examples of gases include things like oxygen, carbon dioxide, nitrogen, hydrogen, helium, steam, and dry ice. Gasses are considered to be far less dense than solids or liquids because the particles in them are much more spread out.
What is gaseous in chemistry?
Gases are the phase of matter in which particles are usually very far apart from one another, move very quickly, and aren't particularly attracted to one another. Because the molecules in a gas are so far apart from one another, gases are much less dense than liquids or solids.

What is an Ideal Gas?
An ideal gas can be described as a gas in which all collisions between atoms or molecules are perfectly elastic in nature and the intermolecular attractive forces between the particles of the gas are not present. One can imagine the particles of an ideal gas as a series of colliding perfectly hard spheres but otherwise not interacting with each other. It is important to note that all ideal gases must obey the ideal gas law. This law equates the pressure exerted by a gas on the walls of its container, the absolute temperature of the gas, the volume occupied by the gas, the amount of gaseous substance (or the number of moles of gas), and the universal gas constant.
What does it mean when the intermolecular distances in a gaseous phase are relatively large?
This means that the gas particles are placed at relatively large distances away from each other. The particles of the gas are in a constant state of random motion.
Why do gases exert pressure on the walls of their containers?
They move around randomly and collide with each other and the walls of the container. Due to the collisions between the gas particles and the walls of the container, all gases are known to exert pressure on the walls of their containers.

What are the laws of gas?
The macroscopic behaviour of gases can be described by Boyle’s law, Charle’s law, etc. To explain the uniformity in the general behaviour of different gases, Bernoulli proposed the kinetic theory of gases, and it was modified by Maxwell, Boltzmann, Clausius and others. The main assumptions of the kinetic theory of gases are: 1 Gases consist of many identical particles (atoms or molecules) that are so small and so far apart on average that the actual volume of the molecules is negligible compared to the empty space between them. 2 The gas particles are always in constant, rapid, random motion in all possible directions and collide with each other and the container’s walls. 3 The molecular collisions are perfectly elastic. 4 The pressure exerted by the gas is due to the collisions of gas molecules with the container’s walls. 5 There is no intermolecular attraction between gas molecules. 6 The volume of the gas molecules is negligibly small compared with the space occupied by the gas. 7 The average kinetic energy of gas molecules is directly proportional to absolute temperature.
Why do gases have a low density?
As the intermolecular forces between the molecules are negligible, gases tend to have a very low density compared to the solid and the liquid states. The density increases with decreasing temperature and increasing pressure.
How do gases compress?
Therefore, the molecules can easily be compressed. It can be done by applying pressure, decreasing its volume and bringing the molecules closer to each other. Thus, the gaps between the molecules reduce, and this makes the gases highly compressible.
What is the arrangement of molecules in matter?
The arrangement of molecules gives matter its physical properties based on which it is classified into solids, liquids, or gases. Out of the three states of matter, it is only in the gaseous state that even the slightest change in physical conditions of temperature or pressure can be observed very easily, which makes this state very interesting.

The amount, volume, pressure, and temperature are the most important properties as these four independent variables ...
Why is pressure exerted by gas?
The molecular collisions are perfectly elastic. The pressure exerted by the gas is due to the collisions of gas molecules with the container’s walls.

What is the difference between liquids and solids?
The primary difference between solids, liquids, and gases is that: Solids (substances that exist in the solid state) have definite shapes and occupy fixed volumes.

Why does an ideal gas have zero intermolecular forces of attraction?
While a real gas has negligible inter-molecular forces of attraction, an ideal gas has zero inter-molecular forces of attraction because the molecules of an ideal gas move so fast, and they are so far away from each other that they do not interact at all.

One difference, though, is that refrigerants are more volatile than gasoline and exist naturally in a gaseous state, so up to 100 percent of a leak could be expected to form a vapor cloud.
