How is the behavior of gases explained?

(N/A) Gases are composed of a large number of atoms or molecules.
The theoretical framework used to explain the macroscopic properties of gases based on their microscopic motion is known as the kinetic theory of gases.
The kinetic theory of gases is based on the assumption that gases consist of atoms and molecules that are in constant,random motion at very high speeds.
In gases,the interatomic (or intermolecular) forces are negligible compared to those in solids or liquids because the particles are far apart,allowing these forces to be ignored in the ideal gas model.
