    Diffusion is one of several transport phenomena that occur in nature. A distinguishing feature of diffusion is that it results in mixing or mass transport‚ without requiring bulk motion. Thus‚ diffusion should not be confused with convection‚ or advections‚ which are other transport mechanisms that utilize bulk motion to move particles from one place to another. In Latin‚ "diffundere" means "to spread out". There are two ways to introduce the notion of diffusion: either a phenomenological approach

    The effect of size on the effectiveness of diffusion Aim: To use agar blocks infused with 0.1 Molar sodium hydroxide (NaOH) and phenolphthalein to investigate the relationship between shape and surface area: volume ratio on the effectiveness of diffusion. Hypothesis: That for a cube of agar‚ the time taken for complete colourisation due to diffusion of HCl is directly proportional to the cubes volume. Materials: |A block of agar (10cm x 5cm x 3cm) with 0.1M NaOH and |1x 250mL

    Experiment 1 Background Diffusion is a process‚ in relation to the spontaneous movement of molecules from an area of high concentration‚ to an area of low concentration down a concentration gradient. It is a type of passive transport method‚ that requires no cellular energy (ATP). This movement occurs‚ until a state of equilibrium has been established on both sides of the membrane. The diffusion of molecules happens at cellular level‚ through a cell membrane via the pores. The cell membrane
