List three phenomenal which support the kinetic theory of matter .
1. Brownian motion: This phenomenon involves the random, continuous movement of particles in a fluid due to their constant collision with other particles. Brownian motion supports the kinetic theory of matter because it demonstrates that particles in matter are in constant motion and are continually transferring their kinetic energy through collisions with other particles.
2. Thermal expansion: When heat is applied to a substance, its particles gain kinetic energy and move faster, causing the substance to expand. This can be seen in various everyday phenomena, such as the expansion of metal when heated or the rising of a liquid in a thermometer when its temperature increases. This supports the kinetic theory of matter because it shows how the motion and energy of particles directly affect the properties of matter.
3. Diffusion: The process by which particles in a substance move from areas of high concentration to areas of low concentration until a uniform concentration is reached throughout. Diffusion occurs both in liquids and gases and can be observed in various situations, such as the spreading of a drop of ink in water or the gradual distribution of a gas throughout a room. This phenomenon supports the kinetic theory of matter because it demonstrates how particles in matter are in constant motion and interact with one another to create uniformity in their distribution.
