| Brownian motion is related to free wobbly motion of particles in a solution but why does it occur? What factors does it depend upon? What is difference between Brownian motion in a gas and a liquid? These and many other questions are answered in this interactive animation for senior classes and college students.

This animation has audio.
Category : Diffusion
Type : Animation with sound
Animation Type : Regular
Total animation length: 11 minute
The animation has following sections:
Why does an atom or molecular particle move?
Is the motion of a particle a straight line?
What is Brownian motion?
Brownian motion depends on which factors?
What happens to the energy of the system during Brownian motion?
What is the difference between a gas's and a liquid's Brownian movement?

| Brownian motion is the cause of many other phenomenon including diffusion, it causes particles to move in a random fashion, many questions on Brownian motion are answered in this section. |

Brownian motion is caused by elastic collision between two particles, Brownian motion can also be caused by collision with walls of a container, how does this alter the path of a particle? What happens to the energy of system during Brownian motion? |
|
A particle will perform a jittery motion and move randomly in Brownian motion, collision with other particles and walls of the container generates further randomnes; increase in the number of particles increases the randomization of path. Over a period of time the particle, undergoing Brownian motion will visit all the points in the enclosed space.
The animation broadly covers the following points:
- Why does an atom or molecular particle move?
- Is the motion of a particle a straight line?
- What is Brownian motion?
- Brownian motion depends on which factors?
- What happens to the energy of the system during Brownian motion?
- What is the difference between a gas's and a liquid's Brownian movement?
The animation explains the process in a clear and lucid manner; it is very easy for the students to understand the process through the animation. |
