state the brownian motion

Answer 1

Brownian motion refers to the random movement of particles suspended in a fluid or gas, resulting from the collisions between the particles and the molecules of the fluid or gas. The particles move in a zigzag or erratic motion, continuously changing direction and speed. This phenomenon was first observed by the botanist Robert Brown in 1827 when he noticed the movement of pollen grains in water. Brownian motion is a fundamental concept in physics and is widely used to describe various phenomena in fields like chemistry, biology, and finance.
