Kinetic Theory
the analysis of matter in terms of atoms in continuous random motion is called the kinetic theory.
For ideal gas, the assumptions which represent the basic postulates of the kinetic theory are:
1. There are a large number of molecules, N, each of mass `m`, moving in random directions with a variety of speeds.
2. the molecules are, on the average, far apart from on another. That is, their average separation is much greater that the diameter of each molecule.
3. The molecules are assumed to obey the laws of classical mechanics, and are assumed to interact with on another only when they collide.
4. Collisions with another molecule or the wall of the vessel are assumed to be perfectly elastic.
