WebJun 8, 2024 · Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. The reverse is true for lighter molecules. Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the … Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of … See more Diffusion is of fundamental importance in many disciplines of physics, chemistry, and biology. Some example applications of diffusion: • Sintering to produce solid materials (powder metallurgy, … See more Fundamentally, two types of diffusion are distinguished: • Tracer diffusion and Self-diffusion, which is a spontaneous mixing of molecules taking place in the … See more Collective diffusion is the diffusion of a large number of particles, most often within a solvent. Contrary to brownian motion, which is the diffusion of a single particle, interactions between particles may have to be considered, unless … See more • Diffusion – Transport of dissolved species from the highest to the lowest concentration region • Ambipolar diffusion See more Diffusion is part of the transport phenomena. Of mass transport mechanisms, molecular diffusion is known as a slower one.
