It is the movement of small particles caused by the fact that air mollecules are moving at high speed and hit the particles. It was firs noticed in pollen by a guy called Brown (so the name). He thought the pollen was moving coz it was alive, so he boiled it, but it still moved.
Dust particles move with Brownian motion due to random collisions with air molecules. These collisions impart random kinetic energy to the dust particles, causing them to move in a zigzag or erratic pattern. This phenomenon helps to explain the seemingly random movement of small particles in a fluid medium.

Added:
Basically heat is the cause of any movement, called kinetic energy.
It is the moving of molecules, ions and/or atoms, randomly hitting to the colloidal (relatively much bigger) particles that is called brownian motion.
Brownian motion is the rapid, erratic motion of particles dispersed in a liquid or gas. This motion is caused by the constant activity of the molecules around the particles.
Brownian movement is due to the constant collision of the molecules of the dispersion medium with that of the pollen grains that are sprinkled on the colloid.
It is due to the bombardment of air molecules on the dust particles.

What is brownian motion and examples?
Brownian motion is the random movement of particles in a fluid due to collisions with other particles in the fluid. This phenomenon was first observed by Robert Brown in the early 19th century when he noticed pollen grains moving in water. Examples of Brownian motion include the random movement of dust particles in the air, the motion of gas molecules in an enclosed space, and the movement of small particles suspended in a liquid.
How did Einstein explain Brownian motion using the moving particle theory?
Einstein explained Brownian motion by proposing that the random movement of particles in a fluid was caused by their collisions with smaller, invisible molecules. This theory helped support the existence of atoms and molecules, providing a quantitative explanation for the observed motion of particles in fluids.
Why the grain of dust moved around in the water?
The movement of a grain of dust in water is due to Brownian motion, where the random collision of water molecules causes the dust particle to move unpredictably. This motion is a result of the thermal energy of the water molecules and is observable on a microscopic scale.
How can you prove that particles of matter are continuously moving?
Particles of matter exhibit Brownian motion, in which they move randomly due to collisions with neighboring particles. This movement can be observed under a microscope as the particles jostle and change position. Additionally, experiments like the Brownian motion experiment conducted by Einstein in 1905 provide further evidence of the continuous movement of particles.
Why do dust particles in the air appear to be moving in different direction's?
Dust particles in the air appear to move in different directions due to variations in air currents and turbulence. This causes particles to be carried in different paths and speeds, leading to their seemingly random movements. Additionally, factors such as temperature differentials, drafts, and obstacles can influence the direction of dust particle movement.
What is the type of erractic motion seen in dust particles suspended in water?
The erratic motion seen in dust particles suspended in water is called Brownian motion. This motion is caused by the random collision of water molecules with the dust particles, leading to their continuous and irregular movement.
What is bvrownian motion?
That would be Brownian motion. That refers to small particles (for example, dust particles) suspended in a liquid or gas exhibiting random behavior - this is caused by liquid or gas molecules bumping into the dust particle.
How do you describe brownian motion?
The rapid zig-zag movement of tiny dust particles suspended in air or in liquid
What are the Evidences of molecular motion?
jittering motions of pollen grains as viewed under a microscope

Why do the dust particles move when a beam of sunlight enter the room?
Dust particles move when a beam of sunlight enters a room due to the heating effect of the light. As the light warms the air around the dust particles, convection currents are created, causing the particles to move and float in the air. This movement is more noticeable in still air where the dust particles remain suspended for longer periods.
Would you Give me two example of brownian?
Brownian motion is the random movement of particles suspended in a fluid, such as dust motes dancing in a sunbeam. Brownian motion is used to describe the erratic fluctuations in the stock market caused by the collective actions of traders buying and selling securities.
What causes particles of a solid to become arranged in a random manner?
When a solid is heated, the particles gain more energy, vibrates faster, and may break free from their ordered arrangement. As a result, the particles move more freely and become arranged randomly to minimize energy and increase entropy.
How did Einstein explain Brownian motion using the moving particle theory?
Einstein explained Brownian motion by proposing that the random movement of particles in a fluid was caused by their collisions with smaller, invisible molecules. This theory helped support the existence of atoms and molecules, providing a quantitative explanation for the observed motion of particles in fluids.
What property of a particle led to the discovery of the atom?
== == Atoms were inferred to exist from the observation of "Brownian motion," which is the jittering of dust particles in air or water or some medium as seen through a microscope. The jitter is supposed to be caused by random collisions of atoms or molecules with the dust particles. If the medium were not composed of particles but were a smooth creamy substance without lumps, there would be nothing to make the dust particles jitter.
How do pollen grains move in water?
pollen grains are attracted by a magnetic force
What waves are caused by colliding air molecules?
Brownian movement, Brownian motion, or pedesis is the random movement of particles suspended in either a liquid or a gas. This is the movement that you see when sunlight is streaming through a window and you see the dust particles randomly moving. This movement helped to prove the existence of atoms and molecules. Many scientists, including Albert Einstein, used this motion to describe movements in the stock market, among other things!
