1.Describe two variables that affect the rate of diffusion
This movement is affected by the size of the particle and the environment the particle is in. Particles will always move around in a medium but the overall rate of diffusion can be affected by many factors. Concentration: Diffusion of molecules is entirely dependent on moving from an area of higher concentration to an area of lower concentration.
2.Describe two variables that affect the rate of diffusion
Factors affecting the rate of diffusion The rate of diffusion depends on three factors: distance – if the diffusion distance is small, diffusion happens faster because the particles do not have as…
3.Describe two variables that affect the rate of diffusion
These are the factors that affect rate of Diffusion; The size of the molecule: The smaller the molecule such as gas, the faster the rate of diffusion while the larger the molecules (liquid) the slower the rate of diffusion. Concentration gradient: The greater the concentration difference, the faster the rate of diffusion.
4.Describe two variables that affect the rate of diffusion
Describe Two Variables That Affect The Rate Of Diffusion The Correlation between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion, various experiments were performedOne of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl).
5.Describe two variables that affect the rate of diffusion
Rate of diffusion is influenced by several factors including temperature, concentration difference and particle size. The diffusion rate is also affected when there is a change in distance between the points where diffusion occurs. Diffusion is the movement of atoms or particles from an area of high concentration to an area of lower concentration.
6.Describe two variables that affect the rate of diffusion
Describe two variables that affect the rate of diffusion. Concentration-As concentration increases, the rate of diffusion increases due to having a higher concentration gradient. Permeability-Membrane permeability affects the rate of diffusion. In the experiment, the membrane permeability was adjusted by varying the molecular weight cutoff (MWCO).
7.Describe two variables that affect the rate of diffusion
Graham’s law: When a gas is dissolved in a liquid, the relative rate of diffusion of a given gas is directly proportional to its solubility in that liquid, but inversely proportional to the square root of its molar mass.
8.Describe two variables that affect the rate of diffusion
Describe two variables that affect the rate of diffusion? … back 2. because urea was too big to pass through the 20 MWCO membrane. front 3. Describe the result of the attempt to diffuse glucose and albumin through the 200 MWCO membrane? back 3. the glucose diffused through the 200MWCO membrane, while there was no diffusion of albumin. front 4 …
9.Describe two variables that affect the rate of diffusion
1. Describe two variables that affect the rate of diffusion. Molecular weight affects the rate of diffusion because the bigger the size of the molecule the longer it will take to diffuse.
1.Physioex 9.0 Cell Transport Mechanisms
1. 2. Describe two Variables that affect the rate of diffusion. The two variables that affect the rate of diffusion are: A. The size of the molecule. The larger molecule will diffuse more slowly than the smaller molecule. B. The nature of plasma membrane.

|1 Factors that Affect Diffusion Rate|
|In this video, we will discuss four factors that affect the rate of diffusion: molecular weight, concentration gradient, surface area-volume ratio, and the temperature.|

Diffusion is driven by a gradient in concentration. The concept of diffusion is widely used in many fields, including physics (particle diffusion),…
2.Fick’s laws of diffusion
Fick’s laws of diffusion describe diffusion and were derived by Adolf Fick in 1855. They can be used to solve for the diffusion coefficient, D. Fick’s…
3.Diffusion of innovations
Diffusion of innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread. Everett Rogers, a professor of…
