First, we must understand what diffusion is! Diffusion is the movement of particles from a high concentration to a lower concentration, in order to reach equilibrium. Cells in particular need this to maintain homeostasis, or an internal equilibrium (stability).
Do you mean molecular size or composition, perhaps? Bigger particles are harder to move than smaller molecules. Additionally, physical constitution of a particle will affect the rate of diffusion. Think of a mouse squeezing under a door as compared to a rock, of the same size. A mouse will more easily be able to squeeze through the gap
Edit
The rate of diffusion is inversely proportional to square root of its inverse of its molecular weight

What three things can affect the rate of diffusion?
Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.
How does pressure affect the rate of diffussion?
Higher pressures cause more molecular collisions which in turn causes a greater rate of diffusion. The opposite is also true - lower pressures cause a decreased rate of diffusion.
Which pair of gas has same rate of diffusion at STP?
Hydrogen and helium have the same rate of diffusion at standard temperature and pressure (STP) due to their similar molecular weights and sizes.
Does the number of villi on a cell affect the diffusion rate?

Does conductivity affect the rate of diffusion?
Conductivity does not directly affect the rate of diffusion in a material. Diffusion is primarily dependent on the concentration gradient of particles in the material and their movement. Conductivity, on the other hand, relates to the material's ability to conduct electricity.
What factors affect the diffusion rate?
Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.

Higher pressures cause more molecular collisions which in turn causes a greater rate of diffusion. The opposite is also true - lower pressures cause a decreased rate of diffusion.
Does the presence of another substance affect the rate of diffusion?
Yes, the presence of another substance can affect the rate of diffusion. Factors like the nature of the substance, concentration gradient, temperature, and molecular size can influence how quickly a substance diffuses in a system.
What factors most affect the rate of diffusion in a liquid or agas?
Two factors which determine the rate of diffusion of a liquid in another liquid include temperature and particle size. The higher the temperature, the faster diffusion takes place, and the smaller the particle, the faster diffusion takes place.
What influences the rate of diffusion?
The rate of diffusion is influenced by the concentration gradient, temperature, molecular size, and the medium through which the particles are diffusing. A steeper concentration gradient, higher temperature, smaller molecular size, and a less dense medium all tend to increase the rate of diffusion.
How a change in medium water to gelatin would affect the rate of diffusion?
A change in medium water to Gelatin would affect the rate of diffusion dramatically. The change from water to gelatin would slow down the rate of diffusion.
Does diffusion terminates at hearth?
Diffusion of molecules will not terminate at the hearth, as it is a continuous process that occurs until equilibrium is reached. However, the specific conditions at the hearth, such as temperature and molecular interactions, can affect the rate and extent of diffusion in that area.
What conditions affect diffusion?
Diffusion is affected by factors such as temperature, concentration gradient, molecular weight/size of particles, and the medium through which the particles are diffusing. For example, higher temperatures generally increase the rate of diffusion, while larger particles diffuse more slowly.
Effect of molecular size on diffusion?
In general, larger molecules diffuse more slowly than smaller molecules because they have a larger molecular weight and therefore experience more resistance from the surrounding medium as they move. This is due to the fact that larger molecules have a lower diffusion coefficient and therefore diffuse at a slower rate. Additionally, larger molecules may also be more prone to interacting with other molecules in their surroundings, further slowing down their diffusion.
The rate of diffusion depends on?
The rate of diffusion depends on the concentration gradient, temperature, molecular weight, and surface area available for diffusion. A steeper concentration gradient, higher temperature, smaller molecular weight, and larger surface area all contribute to faster rates of diffusion.
