    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 advection‚ which are other transport mechanisms that use 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 starting

    supposed to hold up the structure of the cell keeping all organisms in alignment. Osmosis is the movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration‚ in order to equalize the solute concentrations on the two sides. We didn ’t know anything about osmosis except that it was a word in the dictionary that we never picked up. Osmosis and diffusion are similar because osmosis is the result of diffusion across a semi-permeable membrane. If two solutions

This investigation tested the hypothesis: The rate of osmosis will increase as the temperature increases 2x2x2cm cubes of potato were weighed and then placed into 100mL of 10% NaCl solutions for 10 minutes. After 10 minutes the cubes were again weighed to determine the amount of mass that they lost/gained and thus get an indication of the rate of osmosis. The results collected showed that the rate of osmosis was highest in the 70°C solution and lowest in the 20°C solution. From
