What is brownian motion write an activity to show this process??
Answers
Answer:
Brownian motion, also called Brownian movement, any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations. It was named for the Scottish botanist Robert Brown, the first to study such fluctuations (1827).

Explanation:
Brownian Movement in chemistry is said to be the random zig-zag motion of a particle that is usually observed under high power ultra-microscope. This movement resembles the exact motion of pollen grains in water as explained by Robert Brown, hence, the name Brownian movement.
More significantly, Albert Einstein’s later explained the Brownian movement more clearly in his paper stating that the pollen was moved by water molecules. This discovery served as great evidence of the existence of atoms and molecules.
Understanding Brownian movement is crucial as it forms a base for the modern atomic theory. The kinetic theory of gases is also based on the Brownian motion model of particles. Additionally, the mathematical models describing Brownian motion are used in a variety of disciplines such as Maths, Physics, Chemistry, Economics, etc.
What is Brownian Movement?
Brownian movement also called Brownian motion is defined as the uncontrolled or erratic movement of particles in a fluid due to their constant collision with other fast-moving molecules.
Usually, the random movement of a particle is observed to be stronger in smaller sized particles, less viscous liquid and at a higher temperature. These are also some of the factors that affect the movement of particles in a fluid.
One of the most common examples of Brownian motion is diffusion. Cases, where pollutants are diffused in air or calcium diffused in bones can be considered examples of this effect.
Brownian Movement in Colloids
The Brownian motion effect is seen in all types of colloidal solutions. Besides, this phenomenon clearly explains the random motion of sol particles and indicates that these particles are not static. Nonetheless, the main reason for this type of motion in sol particles is due to unequal bombardment of the depressed phase particle leading to non-uniform movement in native due to the difference in the size of the particle.
