what process drives brownian motion
What is Brownian Movement. What Brown observed was that the motion within pollen grains (suspended in water) seemed to move around the liquid seemingly at random. This intrigued him and he began to study why this was happening, and tried to establish what force was driving these random fluctuations and changes in direction.
Brownian motion or pedesis is the random motion of particles suspended in a fluid resulting from their collision with the fast-moving molecules in the fluid. This pattern of motion typically alternates random fluctuations in a particle's position inside a fluid sub-domain with a relocation to another sub-domain. Each relocation is followed by more fluctuations within the new closed volume. This pattern describes a fluid at thermal equilibrium, defined by a given temperature. Within such fluid th
