Kinetic Theory of Matter.
Let us observe a container of matter.We know that a matter is composed of atoms or molecules or ions. Whether all these particles will be in constant motion?
Yes, they do. They are in constant motion.
They move in
i) oscillatory motion / Vibratory motion.
The particles moves to and fro from the mean position.
Eg: particles of solid
ii) Translatory motion
The movement of particles is random,but in particular direction.
Eg: particles of liquid and gases
Whether they move in particular direction?
Yes, they do. They move in a particular direction until or unless it collide with the other particle or hit the wall of the container. This is especially for gas. Since the particles are completely independent of each other
When the particles of matter hit the wall of container, they exert pressure.
All the particles of matter possess some energy due to their result of motion called kinetic energy.
This is called Kinetic Theory of Matter.
Elastic collision:
The total energy of the atom before collision is equal to the total energy of the atom after collision.
