WebbThe rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. In gases, diffusion progresses at a rate of about 5 cm/ min; in liquids, its rate is about 0.05 cm/min; in solids, its rate may be only about 0.00001 cm/min. This slow rate of diffusion is responsible for its importance. Webb16 apr. 2024 · Indeed, ammonia molecules would diffuse randomly and spread throughout the room. Although both Brownian motion and diffusion have to do with the random motion of fluid particles such as air molecules, afaik in physics we don't both lump them together and describes them as separate phenomena. In diffusion, the molecules of one …
