Rate of diffusion increase with the difference of partial pressure of gas between different location. The partial pressure alone is not enough to define what the diffusion rate is, it require difference in concentration or partial pressure.

Name for particles in a gas spreading out?
When the molecules of a gas spread throughout another medium, the process is called diffusion. The rate of diffusion can be influenced by temperature and pressure.
How do you increase diffusion?
One way you can increase the diffusion rate of a system is by increasing the temperature of the system.
How gas diffuses?
Diffusion of a gas is best described using Grahams law of diffusion. It states that the rate of diffusion of gas is inversely proportional to the molecular weight of gas. diffusion generally occurs from a region of high concentration to a region of low concentration. Diffusion occurs in liquids , gases . Generally we sense the smell of chlorine when it is leaked , Here chlorine gas is initially in cylinder at a higher concentration and a higher pressure . Now it is diffused in to surroundings where it have lower pressure and lower concentration.
What si the relationship between carbon dioxide oxygen and alveoli?
Oxygen diffuses into the blood in the alveoli, and carbon dioxide diffuses out of the blood here too. Efficient diffusion is caused by having a thin diffusion distance, high concentration difference and large surface area (of the alveoli), this all means a fast rate of diffusion.
What results would you expect if two model were compare in a diffusion test?
The rate of diffusion would be faster for the right cylinder.
As partial pressure increases what happens to the rate of diffusion?
Rate of diffusion will increase.
How does pressure affect the diffusion rate?
Pressure increases the number of collisions thus increasing the rate of diffusion It speeds up the rate of diffusion
How is diffusion affected by pressure?
Pressure increases the rate of diffusion. As the pressure on the membrane increase, attempts to enter the lower concentration increase, speeding the diffusion rate.
The relationship between density of the medium and diffusion rate?
the lower the density, the faster the rate of diffusion.....
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 is the relationship between the temperature and diffusion rate?
The higher the temperature, the faster the rate of diffusion going down the concentration gradient - Florence
What factors effect the rate of diffusion?
Consintration temperature and pressure
What is the relationship between temperature and diffusion rate?
As temperature increases, the kinetic energy of the molecules increases, so the rate of diffusion also increases.
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.
Rate of diffusion depends upon?
the rate of diffusion depends on the surface area, an increase in the temperature and pressure will result in the increased rate of diffusion. in addition, diffiusion depends on the size of the molecule. the larger the molecule, the slow the rate of diffusion and th smeller the size of the molecule the faster the rate of diffusion.
What is the relationship between molecular size and diffusion rate?
The rate of diffusion depends on the size of the molecule. It can be fast (if molecule is small) or slow (if molecule is large).
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.
