Brownian Motion: Brownian motion is the random movement of microscopic particles in a fluid due to collisions with surrounding molecules. It's like people dancing randomly in different directions at the concert.
Diffusion:Diffusion is the process by which molecules spread out from an area of high concentration to an area of low concentration. It's similar to how perfume spreads and fills up a room.
Kinetic Energy: Kinetic energy is the energy possessed by moving objects. In our analogy, it represents the energy that makes people move and dance at the concert.
