Hint: Brownian movement is the random movement of microscopic particles, which are suspended in a liquid or gas. Brownian movement occurs due to collisions between these particles and the molecules of the liquid or gas.
Complete step by step answer:
In this question, we have asked about the Brownian movement. As we already mentioned that Brownian movement is a random movement of particles due to collision between them. This movement is the same as the motion of pollen grains in water as explained by Robert Brown, hence it is called the Brownian movement but the complete theory is explained by Einstein. The true solution doesn't have Brownian movement because the particles are so small and homologous and they move uniformly. So, the Brownian movement is found in all types of colloidal solutions. Due to the collision of colloidal particles, they acquire kinetic energy equal to that of the molecules of the medium. This Brownian movement is important because due to the continued zigzag motion of the particle, they do not settle down and coagulation does not occur. Some factors affect Brownian movement like smaller sized particles, less viscous liquid and at a higher temperature, more Brownian movement is seen. An Example of Brownian movement is the movement of pollen grain in oil droplets.
Note: Always remember that Brownian motion is different from diffusion as Brownian movement is the random motion of particles of matter in the air and liquid while diffusion is the process of intermixing of two substances.
