Avi Nandi said:For observation of Brownian motion, the mass and the size of the Brownian particle should be very small. Within what range the size and mass of the Brownian particle should lie?? Can a particle with small mass and bigger size and vice versa can undergo Brownian motion??
Brownian motion is the random movement of particles suspended in a fluid. It was first observed by the scientist Robert Brown in the 19th century.
Brownian motion occurs due to the collision of fluid molecules with the particles. These collisions result in a random, erratic movement of the particles.
The mass of a Brownian particle has a direct impact on its motion. Heavier particles will move slower and have less frequent changes in direction compared to lighter particles.
The size of a Brownian particle also affects its motion. Smaller particles will experience more frequent collisions with fluid molecules, resulting in a faster and more erratic motion compared to larger particles.
Brownian motion is directly related to temperature. As the temperature increases, the fluid molecules have more energy and collide with the particles more frequently, leading to a faster and more pronounced Brownian motion.
