Question

Write any three postulates of the kinetic theory of gases?

Answer 1

Hint: To answer this question first you should know that the Kinetic theory of gases is a theoretical model that describes the molecular composition of the gas in terms of a large number of submicroscopic particles which include atoms and molecules.

Complete step by step answer:
You should know that the kinetic theory of gases explains that gas pressure arises due to particles colliding with each other and the walls of the container. It also defines properties such as temperature, viscosity, and thermal conductivity, and all these properties are related to the microscopic phenomenon.
The significance of this theory is that the kinetic theory of gases also helps us study the action of the molecules. Generally, the molecules of gases are always in motion and they tend to collide with each other and the walls of the containers.
The kinetic theory of gases can be stated as three postulates:
-The particles of a substance constantly move in random motion, and during this random motion, they collide with each other and with the walls of the container.
-All collisions between gas molecules are perfectly elastic; all kinetic energy is conserved.
-During two successive collisions, the average distance moved by the particle (between two collisions) is called 'mean free path'.

Therefore, we described the three postulates of the kinetic theory of gases.

Note: The other postulates of the kinetic theory of gases are -
-The average kinetic energy of the particles is directly proportional to its absolute temperature.
-Gas molecules influence each other only by collision; they exert no other forces on each other.
