Applied science - Diffusion 0.0 / 5 ? Applied ScienceDiffusionBTEC NationalNone Created by: Joseph45Created on: 10-10-19 12:11 What is diffusion? Diffusion is where molecules move from a area of high concentration to an area of low concentration. 1 of 6 How long does diffusion last for? Diffusion continues until the concentration is equal. this is called dynamic equilibrium. 2 of 6 Can diffusion take place in solids? No, only liquids and gases. Diffusion is faster in gases. 3 of 6 What happens to the rate of diffusion if there is a big difference in concentration? Diffusion will be happening faster. 4 of 6 What happens if we increase temperature? The amount of kinetic energy will increase, resulting in more collisions, causing the rate of diffusion to increase. 5 of 6 Are small molecules faster than large molecules? Yes, due to this the rate of diffusion increases. This is because there will be more collisions. Molecules with a stream lined shape move faster. 6 of 6
