Answer:-
The kinetic theory of matter states that all matter is made up of tiny particles—atoms and molecules—that are constantly in motion. The speed of these particles depends on the temperature; higher temperatures make them move faster, while lower temperatures slow them down. This theory explains the different states of matter: in solids, particles vibrate in place; in liquids, they move more freely; and in gases, they move rapidly in all directions. It also helps explain concepts like pressure, diffusion, and heat transfer. Essentially, the kinetic theory describes how particle motion influences the physical properties of matter around us.
