State the assumptions on which kinetic theory of gas is based. |
|
Answer» Assumptions of kinetic theory of gases: (i) All gases consist of molecules. The molecules are rigid, elastic spheres identical in all respects for a given gas and different for different gases. (ii) The size of a molecule is negligible compared with the average distance between two molecules. (iii) The molecules are in a state of continuous random motion, moving in all directions with all possible possibilities. (iv) During the random motion, the molecules collide with one another and with the walls of the vessel. (v) The collisions are perfectly elastic and there are no forces of attraction r repulsion between them (vi) Between two collisions, a molecule moves in a straight path with a uniform velocity (vii) The collisions are almost instantaneous. (viii) The molecular density remains uniform through out the gas. |
