Diffusion particles can vary in size, ranging from nanoparticles (1-100 nm) to larger molecules or particles. The size of a diffusion particle affects its movement and speed in a medium. Smaller particles generally diffuse more rapidly than larger ones due to their higher mobility.

What are the particle involved in diffusion?
Diffusion is due to the Transitional movement of molecules or particles.
What reactions are affected by particle size?
Particle size can affect various reactions such as dissolution rate, surface area available for reaction, and diffusion rates. Smaller particle sizes increase the surface area, leading to faster reactions, while larger particle sizes can reduce the reaction rate due to lower surface area available for reaction.
Does a larger distance does it speed up the rate of diffusion?
No, increasing the distance between particles does not speed up the rate of diffusion. In fact, diffusion rate is influenced by factors such as concentration gradient, temperature, and particle size but not necessarily distance alone. The rate of diffusion is generally slower over larger distances.
What is one part of the particle theory that is important to diffusion?
One important part of the particle theory for diffusion is that particles are in constant random motion. This motion allows particles to spread out and mix with other particles in a process known as diffusion.
Explain why diffusion is evidence for particle models?
Diffusion occurs because particles move randomly in all directions until they are evenly distributed. This can be explained by the particle model, which states that matter is made up of tiny particles that are constantly in motion. The movement of particles in diffusion supports the idea that substances are composed of particles that are constantly moving.
What factors affecting the diffusion?
There several physical factors that affect the rate at which particles diffuse. These include: the size of the particle, the temperature, the concentration difference, the diffusion distance, the surface area, and permeability.
What the intermixing of particle are known as and why?
diffusion
What are the particle involved in diffusion?
Diffusion is due to the Transitional movement of molecules or particles.
What does the diffusion of gases tell us about their particle size?
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.
A phenomena that can be explained with the particle model?
Diffusion
What reactions are affected by particle size?
Particle size can affect various reactions such as dissolution rate, surface area available for reaction, and diffusion rates. Smaller particle sizes increase the surface area, leading to faster reactions, while larger particle sizes can reduce the reaction rate due to lower surface area available for reaction.

What factors most affect the rate of diffusion in a liquid or agas?
The factors that most affect the rate of diffusion in a liquid or gas are temperature, molecular weight of the particles, concentration gradient, and medium through which particles are diffusing. Higher temperature and lower molecular weight increase the rate of diffusion, while a steeper concentration gradient promotes faster diffusion. The type of medium can also impact the rate of diffusion based on its viscosity and other properties.

What is the difference between particle size and crystallite size?
Particle size refers to the overall size of the individual particles in a material, while crystallite size specifically refers to the size of the crystalline regions within a material. Crystallite size is related to the arrangement of atoms within a material, while particle size is a more general measure of the physical dimensions of the particles.
