Why must particles be extremely small to demonstrate Brownian movement?
Particles must be extremely small to demonstrate Brownian movement because their tiny size allows them to be significantly affected by the random collisions with the much larger and more numerous molecules of the surrounding fluid. This random motion becomes evident only when the particle is small enough that these collisions impart noticeable displacement. Larger particles would experience reduced relative motion, as their inertia would dominate, masking the effects of these random collisions. Thus, the scale of the particles is crucial for observing the erratic, jittery movement characteristic of Brownian motion.
Why do nanoparticles move differently to larger particles?
Nanoparticles have a higher surface-area-to-volume ratio, making them more prone to surface interactions, such as adhesion and attraction, which can affect their movement. Additionally, nanoparticles experience more Brownian motion due to their smaller size, causing them to exhibit different diffusion behaviors compared to larger particles.
How particles would move in gel electrophoresis according to size?
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
Particles move randomly and are well spaced out?
In a gas, particles move randomly due to collisions with other particles and the container walls. The spacing between gas particles is relatively large compared to the size of the particles themselves. This randomness and spacing contribute to the properties of gases, such as their ability to expand to fill a container.
Why do different size particles move at different speeds?
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.
Why is Brownian motion more intensive in higher temperature?
Brownian motion is the "jiggling" of macroscopic particles due to their bombardment by surrounding molecules as they move around. The direction of the force of atomic bombardment is constantly changing, and at different times the particle is hit more on one side than another, leading to the seemingly random nature of the motion. The size of the particles that can be thus affected is so small that it requires a microscope to observe the effect. As the temperature of a liquid or gas increases, the average velocity of the molecules increases. Faster motion means increased momentum for the molecules impacting the macroscopic particles, thus as temperature increases, so does Brownian motion.

Which way does the particles move in a ocean wave?
In an ocean wave, water particles move in a circular motion. As the wave passes through, water particles move in an elliptical path, with the motion decreasing in size as it gets deeper. The circular motion of water particles is what helps transport energy across the ocean surface.
Do individual particles of a medium move as a wave moves?
No, individual particles of a medium do not move along with a wave. Instead, they oscillate back and forth in a motion perpendicular to the direction of wave propagation. This motion of particles helps to transfer the energy of the wave through the medium.
Do particles in a colloidal system are affected by gravity?
Yes, particles in a colloidal system can be affected by gravity. However, due to their small size and the surrounding medium (usually a liquid), the effects of gravity can be minimized compared to larger particles. Brownian motion and other forces at the particle level can also counteract the influence of gravity.
What happens to the particles in colloids?
A colloid has particles small enough that they will never settle out; brownian motionkeeps them in suspension. A colloid shows the Tyndall effect. An emulsion or suspension has droplets or particles which, due to their larger size, separate from a suspension.to form a layer or precipitate.
Does the size of an atom determine whether an element is a solid or liquid or gas?
The different states (which are solids, liquids and gases) are determined by the amount of energy present in the system. Energy is found in several forms, but kinetic energy is the form that the state of matter takes on, especially when it is changed from one state of matter to another. The various states of matter are always in constant motion. In liquids and gases, the motion known as the Brownian motion occurs. This is where particles move randomly while suspended. Even in solids, the particles continue to move, but is a vibration around a fixed point, and is not as free as the liquids and gases. Hope that helped!! <(^_^)>

Are molecules in the air visible?
A1. yes they areansw2. Albert Einstein worked on the Brownian motion of (visible) dust particles in the air. This was one of his early investigations.You should try and find this research, as it is an excellent example of a simple but profound experiment. try 'Brownian Motion' in your favourite search engine.
What is a postulate of the kinetic-molecular theory?
all particles are always moving
What is the size of a particle?
It is very very tiny and microscopic that you can not see it. Even though you can not see it the particles still move. Solids have particles packed tightly together and vibrating in motion. Liquids have particles flowing and farther apart from each other. Gas particles move so fast and are moving randomly and are so far apart from each other. This is the dimension of a particle expressed as diameter, mass, volume.
Why do solids stay the same size?
becuz the particles don't move
