How do gases differ from solids and liquids?

Solution

There are three main natural physical states of matter, they are Solids Liquids, and Gases.
Solids Liquids Gases
They are the rigid states of matter, having regular arrangement of particles giving rise to matter with a fixed shape and volume.
Liquids are fluid states of matter with a fixed volume, but they do not have a fixed rigid shape.
Gaseous state is a state of matter that has neither a fixed shape nor a fixed volume.
The constituent particles in solids are closely packed by a strong intermolecular force of attraction.
The intermolecular force of attraction between the constituent particle is less, hence they are loosely packed together
The constituent particles in the gas are very loosely packed due to the very low intermolecular force of attraction among them.
The constituent particles show almost no mobility, they just exhibit vibrational motion at elevated temperatures.
The constituent particles can show mobility and they can easily flow.
Therefore gases can freely move with higher kinetic energy.
Solids are incompressible.
Example: Glass, Rock, Wood, etc.
Liquids are not very compressible.
Example: Water, Oil, Milk, etc.
They can easily flow. Gases are highly compressible.
Example: Oxygen(O₂), Hydrogen(H₂), etc.
