State the assumptions of kinetic theory for ideal gases
Answers
Answer:
Assumptions of Kinetic Theory of Gases:
The separation between the molecules is much greater than the size of molecules. ... All the collisions between molecules and even between molecules and wall are considered to be elastic. All the molecules in a certain gas sample obey Newton's laws of motion.
Answer:
Basics of Kinetic Theory
It says that the molecules of gas are in random motion and are continuously colliding with each other and with the walls of the container. All the collisions involved are elastic in nature due to which the total kinetic energy and the total momentum both are conserved. No energy is lost or gained from collisions.
Assumptions
The gas consists of a large number of molecules, which are in random motion and obey Newton’s laws of motion.
The volume of the molecules is negligibly small compared to the volume occupied by the gas.
No forces act on the molecules except during elastic collisions of negligible duration.
At the ordinary temperature and pressure, the molecular size is very very small as compared to the intermolecular distance. In case of gas, the molecules are very far from each other. So when the molecules are far apart and the size of the molecules is very small when compared to the distance between them. Therefore the interactions between the molecules are negligible.
In case there is no interaction between the molecules than there will be no force acting on the molecule. This is because it is not interacting with anything. Newton’s first law states that an object at rest will be at rest and an object will be in motion unless an external force acts upon it.
So in this case, if the molecule is not interacting with any other molecule then there is nothing that can stop it. But sometimes when these molecules come close they experience an intermolecular force. So this basically something we call as a collision.
