That happens when - as is the case in a gas for example - the distribution of probabilities, when graphed, is not symmetric. The "most probable particle speed" probably refers to the maximum of the curve, and this is not necessarily equal to the average.
In a vacuum, the size of particles is not affected by size, but when the particles are moving through a fluid such as air or water, the resistance of the fluid will affect their motion. In general terms, the friction between the particle and the fluid will be proportional to the surface area, but the mass will be proportional to the volume so doubling the dimensions will multiply the surface area by a factor of 4 but multiply the volume (and hence mass) by a factor of 8. As particle size increases, the kinetic energy and the momentum increase faster than the surface area so the friction between the particle and the fluid has less effect proportionately. Sand falls faster than dust for this reason.
it is different because the size.
Assuming you mean rate of reaction. The factors are particle size, concentration, temperature and catalyst. The smaller the particle size the bigger the surface area exposed, so more particles are available for reactions to occur. The higher the concentration the more particles present so more reactions take place. The higher the temperature the faster the particles move around so there are more frequent reactions between particles. Having a catalyst present speeds up a reaction without the catalyst being used up.
During gel electrophoresis, the smaller particles move faster than the larger ones. The end of the gel where the samples are loaded is called the sample origin. Samples move from the origin toward the opposite electrode according to size. At the end of the run, smaller particles will have migrated farther from the origin and the larger ones will be found closer to the origin
The most basic answer would be that they dont have the same properties as the bulk material and these particles in the nm size range are governed by quantum mechanics.
The size of the particles that can be absorbed in Biology are very small sized particles.
Different cells move at sightly different speeds, but due to their size, it is very slow.
Liquids cannot stay the same size size because the particles inside the liquids have some bit of space to move to a different shape and to change the size.
it is different because the size.
becuz the particles don't move
Sieve.
A suspention is a solution where the particles of the solvent(liquid) are a different size to the particles of the solute(Solid).
The cell is the slowest moving particle because of its weight and its size.

When particles are heated or cooled, they do not change size at all. They simply move with greater kinetic energy so the space between particles increases. This prompts the changes in size we see when substances are heated or cooled.
all particles are always moving
Sand particles are in fact a variety of sizes on the same beach front. This is because these sand particles are formed at different times through different processes.
