→ Brownian Motion: The zig-zag or random path travelled by the particles of matter is called Brownian motion.
→ Intermixing of particles of two different types of matter on their own is called diffusion.
The rate of diffusion increases on increasing the temperature of the diffusing substance (by heating).
Example - The colour of ink spreading in water due to diffusion of particles of water.
