because they have a larger mass and require a greater energy to move at the same speed.
KE=1/2mv2 where m is mass, v is velocity and KE is kinetic energy
so for the same energy if the mass is doubled then v2 is halved, resulting in a slower speed
Thermal expansion
In a solid, the particles start to vibrate a lot.In a liquid, the particles begin to move around faster and faster.In a gas, the particles move extremely fast through the air.
Change states
Particles move at a faster rate at higher temperatures, than they do at lower temperatures. This is do to the fact that heat is a form of energy. When a particle has more energy is moves faster.
Smaller DNA segments move more easily through the gel. (APEX)
In general, smaller particles move faster than larger ones due to their higher kinetic energy at a given temperature. However, the frequency and force of collisions depend on factors such as particle concentration and temperature, not just particle size. Smaller particles can indeed collide more frequently but not necessarily more forcefully than larger particles.
Smaller particles have less mass, so they experience less resistance from the water molecules. This allows them to move faster through the water compared to larger particles which have more mass and therefore experience more resistance.
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
In general lighter particles should diffuse faster than heavier particles, this could be extrapolated from the relationship to mass, volume, and energy. If we look at particles of all the same, ideal, substance, we would see that an object with less mass would be smaller but would also require less energy to move. That is, at the same temperature a particle of lower mass would move faster than a similar particle of heavier mass. We also see that smaller particles also maximize surface area/mass - this is also conducive to faster diffusion.
The diffusion of gases is inversely proportional to their particle size. Smaller gas particles diffuse more rapidly compared to larger gas particles. This is because smaller particles can move more easily through empty spaces between other particles, allowing them to spread out faster.
particles move faster in a liquid when there's More added to it
In a vacuum, there is no air resistance or friction to slow down the particles, allowing them to move faster without any impediments. This lack of resistance enables the particles to move freely and at their maximum speed.
Particles move faster in a gas than in a liquid. In a gas, particles are more spread out and have more kinetic energy, leading to faster and more random movement compared to the more orderly and slower movement of particles in a liquid.
Thermal expansion
slow
Water typically flows faster through gravel compared to soil. This is because gravel has larger pore spaces between particles, allowing water to move more freely. Soil, on the other hand, has smaller pores and more fine particles that can slow down the flow of water.
No. Gas particles move much faster than solid particles.
