An Investigation to Observe the Effect of Different Sugared Solutions on the Mass of Potato Tubes Introduction: Diffusion is the natural random movement of gas and liquid particles, from a high concentration of that substance to a low concentration. An example of diffusion in body is in the lungs. Oxygen in the alveolar air spaces diffuses in to the blood capillaries. Osmosis it the diffusion of water particles through a partially permeable membrane, from an area of high concentration to an area of low concentration. This is until an equilibrium is formed. 'The movement of molecules of a solvent through a semi permeable membrane' (Usborne Dictionary of Science) Prediction: I predict that the potato tubes that have high sugar content will loose the most mass this is because there will be a higher level of water in the potato tubes than in the solution and osmosis moves from high to low concentration....
