give the postulate of kinetic theory of gases

POSTULATES OF KINETIC THEORY OF GASES....
1.Gases are composed of a large number of particles that behave like hard, spherical objects in a state of constant, random motion.
2.These particles move in a straight line until they collide with another particle or the walls of the container.
3.These particles are much smaller than the distance between particles. Most of the volume of a gas is therefore empty space.
4.There is no force of attraction between gas particles or between the particles and the walls of the container.
5.Collisions between gas particles or collisions with the walls of the container are perfectly elastic. None of the energy of a gas particle is lost when it collides with another particle or with the walls of the container.
6.The average kinetic energy of a collection of gas particles depends on the temperature of the gas and nothing else...

Answer:
Kinetic theory of gases provides the sound theoretical basis for the various gas laws.
The kinetic theory of gases is based on the following postulates:-
(i) The actual volume of the gas molecules is negligible in comparison to the total volume of the container in which it is kept.
(ii) There are no interaction between the gas molecules.
(iii) The gas consists of extremely small particles which are in constant random motion.
(iv) The particles of gas collide with each other and with the walls of the container.
(v) The collisions are perfectly elastic.
(vi) Different particles of the gas, have different speeds.
(vii) The average kinetic energy of the gas molecules is directly proportional to the absolute temperature.
