I can explain how particles spread through a fluid.
Show transcript
Brownian motion is the random motion of particles suspended in a medium.
Particles of a substance released into a fluid (a gas or liquid) move around and are pushed by other particles.
Substances that have particles that are free to move will eventually reach a random distribution throughout.
At higher temperatures, particles in a gas or solution move more quickly.
