Question

What is Brownian motion? Draw a diagram.

Answer 1

Brownian motion

1. The random motion by small particles suspended in the fluid is known as Brownian motion.
2. It is a zig-zag motion of the particles.
3. The particles move randomly as they are bombarded by the other particles in the liquid.
4. This motion can occur even without any external force applied.
5. It is a type of diffusion we can say as the movement of particles occurs from their higher concentration to their lower concentration.
