The rate of diffusion increases as temperature increases.Hence, the rate of diffusion will be the greatest in boiling water then warm water and cold water at last
- The movement of molecules along a concentration gradient is known as diffusion.
- It is a significant process that all living things go through. Diffusion facilitates the flow of materials into and out of cells.
- Increased energy from higher temperatures causes the molecules to move more quickly, speeding up the diffusion process.
- Lower temperatures cause the molecules' energy to drop, which lowers the diffusion rate.
- The rate of diffusion increases with increasing concentration differences.
- The particles will move and mix more quickly at a greater temperature because they will have more kinetic energy.
Hence, the diffusion rate will be boiling water>warm water>cold water
