Diffusion is the movement of particles across a selectively permeable membrane, from a high concentration to a low concentration. So the larger the surface area, the quicker the rate of diffusion because there is more space to diffuse in.

∙ 11y agoThe more surface area you have the more effective diffusion is, but diffusion also depends on the volume of the object. For example if a sphere and a thin sheet of paper have the same surface area the paper will reach equilibrium faster because the paper has a bigger surface area to volume ratio.

∙ 9y agoDiffusion is the movement of materials from an area of higher concentration to an area with a lower concentration. The larger the surface area, the faster the diffusion rate.

What influences the rate of diffusion?
The rate of diffusion increases with temperature. The rate of diffusion also increases with the concentration gradient and the surface area.
What are the factors which affect rate of diffusion?
the factors which affect rate of diffusion is the factors that mixing one substance to another.
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.
How does surface area affect the rate of cooling?
the color of an object will affect the rate of cooling e.g black objects cool down faster than shiny objects, the temperature around the object will also affect the rate of cooling, if the surrounding is cold, a hot object will cool faster than when the surrounding is hot.
Why does stirring affect diffusion?
Stirring decreases the time it takes for a substrate to dissolve in a solvent. More of the substrate is exposed to the solvent, thus, allowing it to dissolve quicker. This is similar to why increasing surface area during a chemical reaction, increases the rate of the reaction.
How does surface area to volume ratio of a cell affect rate of diffusion?
The surface area to volume ratio of a cell affects the rate of diffusion in that the higher the ratio, the faster the rate of diffusion. This is a directly proportional relationship.
What influences the rate of diffusion?
The rate of diffusion increases with temperature. The rate of diffusion also increases with the concentration gradient and the surface area.
What factor affects 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.
What is the relationship between surface area to volume ratio and the rate of diffusion?
The higher the ratio, the faster the rate of diffusion
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.
Why is a large surface area necessary for the alveoli in the lungs?
According to fick's law rate of diffusion =(proportional to)= Surface area x Diffusion gradient Diffusion Pathway thickness So for a sufficient rate of diffusion, Surface area must be large The diffusion pathway is already at it's minimun of 1 cell thick and the gradient is harder to adjust. There are around 600 million alveoli in the lungs that have a cummulitive surface area of around 70m2.
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.
What is diffusion rate proportional to?
rate of diffusion depends on the concentration gradient, surface area, distance over which diffusion takes place, size and nature of the diffusing molecule.
How does the surface area of a rock affect the rate of weathering.?
The surface area of a rock has a big affect on the rate of weathering. The higher the surface area of the rock in proportion to its overall mass will result in a quicker rate of weathering of the rock.
How does the surface affect the rate of weathering?
more surface area= faster rate of weathering
Where surface area is not affect the rate of a reaction?
Surface area affect the reaction rate because the contact between finely divided particles is improved.
What is diffusion in the villi?
Same as anywhere else on the cell. The function of the villi is to increase the surface area, and thus the rate of diffusion.
