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.
One way you can increase the diffusion rate of a system is by increasing the temperature of the system.
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.
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.
The rate of diffusion would be faster for the right cylinder.
Rate of diffusion will increase.
Pressure increases the number of collisions thus increasing the rate of diffusion It speeds up the rate of diffusion
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 lower the density, the faster the rate of diffusion.....
The higher the ratio, the faster the rate of diffusion
The higher the temperature, the faster the rate of diffusion going down the concentration gradient - Florence
Consintration temperature and pressure
As temperature increases, the kinetic energy of the molecules increases, so the rate of diffusion also increases.
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.
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.
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).
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.
