Write the Kinetic theory assumption of gases.
Following are the fundamental assumptions of kinetic theory of gases:
-
A gas is composed of a large number of tiny invisible, perfectly elastic particles, called the molecules.
-
The molecules are always in a state of continuous motion with varying velocities in all possible directions.
-
The molecules traverse the straight path between any two collisions.
-
The size of the molecules is infinitely small compared to the average distance traversed by a molecule between any two consecutive collisions . The distance between any two consecutive collisions is called the free path and the average distance between any two consecutive collisions is called the mean free path.
The time of collisions is negligible as compared with the time taken to traverse the free path.
The collisions between molecules and with the walls are perfectly elastic so that there is no loss of kinetic energy in the collisions.
The molecules exert no force on each other except when they collide and the whole of the molecules energy is kinetic.
The volume of the molecules is negligible as compared to the volume of a vessel containing gas.
The inter molecular distances in a gas is much larger than that of a solid or liquid and the molecules of a gas are free to move in the entire space available to them.
