This presentation discusses diffusion and the factors that influence the rate of diffusion. It explains that diffusion occurs most rapidly in gases, more slowly in liquids, and very slowly in solids. The rate of diffusion is affected by temperature, particle size, and particle mass - with higher temperatures, smaller particles, and lower masses increasing the rate. Examples provided include the permeation of perfume in a room, the smell of incense burning, and the fragrance of flowers.
Rate of diffusion
- 1. Chemistry Activity, research work…
- 2. This presentation is on increasing order of rate of diffusion of various substance
- 4. Rate of diffusion in solid, liquid and gas Diffusion takes place very rapidly in case of gases, to a lesser extent in case of liquids, and not at all in the case of solids. However, diffusion in does take place, liquidsparticles Solid Liquid particles albeit at a very slow rate. Gas particles
- 5. Factors influencing rate of diffusion • Temperature: As temperature increases, the kinetic energy of the particles increases. Thus, the speed of particles also increases, which in turn increases the rate of diffusion. • Size of the particle: As the size of particle increases, rate of diffusion decreases. This is because the particles become less mobile in the solvent. • Mass of the particle: As the mass of the particle increases, the rate of diffusion decreases; as the particle becomes less mobile.
- 6. Examples of diffusion from our daily life… • Cologne or perfume permeating the air in a room. Spraying of perfume • Burning of agarbatti (coil). Burning of agarbatti (coil).
- 7. • Boiling of milk. • Smell of a food. • Fragrance of a flower. Fragrance of a flower.
