Hi, Can anyone explain what is known as "The Brownian Movement".Is it something to do with liquids? ? Help!
Answers:
Im not sure, but im about to have a Brownian Movement myself.
zigzag, irregular motion exhibited by minute particles of matter when suspended in a fluid
Do Yahoo or any search for more details

The brownian movement is caused by not wiping your bum and not changing your undies often enuff!
Not just in a liquid gas particles exhibit Brownian motion too.
i think u mean brownian motion. it is defined as "the erratic random movement of particles as a result of continuous bombardment by the surrounding medium". in other words, if u place some pollen grains in a glass of water, u will observe brownian motion. this is when particles of matter (for example, pollen grains placed in water) move erratically and randomly (in no specificdirection or speed) as a result of bombardment by their surrounding medium (the medium, or matter, that surrounds them)(in this case, it's the water). this does not only occur with liquids. for example, you can observe it with dust in air or smoke particles in air.
i guess that it is when moiecules of any liquid move to become gas or in solid form
Brownian motion is simply the helter-skel;ter movement of any type of particles in a fluid, i.e both gas and liquid.it is when particles are moving in a straight line and all of a sudden change direction. This is because they collide with other similar or non-similar particles in the environment and are forced to change directions.much like when you collide two marbles or balls and they change directions..only thet there are too many other particles around and therefore collisions are more often. A man named Robert Brown (not sure of Robert) discovered it.

BROWNIAN MOVEMENT IS THE MOTION OF COLLOIDAL PARTICLES. I HOPE YOU KNOW WHAT A COLLOID IS. IT IS EXHIBITED BY COLLOIDS ONLY. EXAMPLES OF COLLOIDS ARE BLOOD, MILK ETC. COLLOIDS EXHIBIT THE PROPERTY OF BROWNIAN MOTION WHEN VIEWED UNDER A MICROSCOPE; WHICH IS THE ZIG ZAG MOTION OF THE PARTICLES. COLLOIDS ALSO EXHIBIT THE PROPERTY OF SCAETTERING EFFECT.
Yes its the random motions of liquids and gases. Like a lot of discoveries it was discovered by accident. The plan was to experiment with water which wasn't moving, no vibrations caused by movement in the lab etc. but it just wasn't happening, basically you can't do it.
Brownian motion is the name given to the random movement of molecules in a liquid or a gas.
named after robert brown from montrose scotland, he first noticed that tiny particles such as soot, or smoke, were constantly moving when observed through a microscope.
the reason they moved was because they were continually being bombared by air particles (which are far too small to see under the microscope). however it proves the existance of air, and that the air particles are continually moving.
Try it out yourselve if you have a microscope and a small see through container that will fit under a microscope. Capture some smoke into the container, seal it and view, its quite theraputic watching the smoke particles zig zag around in apparently random movements
Many have come close to the answer but have not answered it completely. True, Brownian movement is the apparently random movement of microscopically small particles suspended in a medium such as a gas or liquid. What the others did not explain is that the movement of the suspended particles is the result of their colliding with molecules of the medium in which they are suspended.
In simple terms it is the random, erratic movement of a big particle(e.g. smoke) when constantly being bombarded by smaller molecules(e.g. air molecules) from all directions in varying velocity(thus different force exerted). Acondition would be the bigger particles in in a fluid. Think the thing that has something to do with water is the discoverer started off from looking at pollen grains moving in haphazard manners in water.
If you put pollen particles in a drop of water under a microscope, the particles will all be moving about randomly, as they are buffeted by the invisible water molecules. This is Brownian Motion.
Brownian motion is the random movement of large particles due to random impacts with smaller particles. The large particle (eg a smoke particle or pollen grain) is seen to move in a random, zig-zag path due to collisions from the smaller, invisible particles (air molecules or water molecules respectively). By invisible, i mean that whilst individual large particles can be seen, individual small particles cannot. This is why Brownian motion confused Brown when he observed it; he couldn't figure out why the large particles were moving randomly! It is only if you introduce ideas of sub-microscopic particles in constant motion that Brownian motion can be explained.
Incidentally, to conserve momentum, the large particles undergo smaller changes in velocity than the smaller particles, because they are less massive.
hope this helps.
