WebDiffusion occurs through the membrane but as the cell size increases the surface area to volume ratio decreases. This means the rate of diffusion slows down, the process of diffusion is useful to cells so if they don’t get nutrients in or waste out fast enough they die. WebThe rate of diffusion depends on three factors: distance - if the diffusion distance is small, diffusion happens faster because the particles do not have as far to travel

2.9: Graham

WebThe lighter gases pass through the small openings more rapidly (at a higher rate) than the heavier ones (Figure 9.29). In 1832, Thomas Graham studied the rates of effusion of different gases and formulated Graham’s law of effusion: The rate of effusion of a gas is inversely proportional to the square root of the mass of its particles: WebDiffusion and Fluid Flow What determines the diffusion coefficient? 1.

WebApr 8, 2024 · Graham’s law thus states that the square root of the molecular mass is inversely proportional to the rate of diffusion. The expression for the Graham’s law of diffusion is as follows: r 1 r 2 = M 2 M 1. Where, r 1 and r 2 are the rates of diffusion, M 1 and M 2 are the molecular masses. We know that higher the molecular mass bigger is the ... WebDiffusion and Molecular Mass. Explore the role of a molecule's mass with respect to its diffusion rate. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion.

"WebFeb 2, 2011 · The higher the pressure, the denser is the molecule packing, the less is the free-path length, and the slower is the diffusion. The same occurs as molecule mass and size increase. Conversely, elevation of temperature causes an increase in the free-path length, a decrease in the number of collisions, and growth of free-motion velocity.

WebMass affects the rates of diffusion and effusion because an element will diffuse slower if its a larger, heavier element an element will diffuse faster if its small and lighter. Why does … WebOct 21, 2015 · As the ratio gets smaller, it takes longer for items to diffuse. Explanation: When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective.

WebThe rate of diffusion is influenced by both temperature (how fast the particles move) and size (how big they are).
