This answer is: WebApr 8, 2024 · Solid, liquid or gas, diffusion can take place in any of these media. Osmosis can take place only in a liquid medium. No requirement of a semi-permeable membrane for diffusion to occur. A semi-permeable membrane is a must for osmosis to take place.

WebDiffusion occurs when particles spread. They move from a region where they are in high concentration to a region where they are in low concentration. Diffusion happens when the particles are free to move. This is true in gases and for particles dissolved in solutions – but diffusion does not occur in solids. Why does diffusion occur in gases? WebDiffusion happens the fastest in gases, however it can happen in solids, liquids as well. The rate of diffusion depends on factors such as temperature and the element being diffused. With an increase in temperature, the diffusion rate speeds up as the molecules get more energy and move quickly then after. A theory suggests that polar materials ...
