Semipreameable membrane is by diffucion
WebOsmosis is a special case of diffusion. Water, like other substances, moves from an area of higher concentration to one of lower concentration. Imagine a beaker with a semipermeable membrane, separating the two sides or halves (Figure 3.25). On both sides of the membrane, the water level is the same, but there are different concentrations on ... WebApr 8, 2024 · Diffusion refers to the process in which particles from a higher concentration tend to move or transport to a lower concentration medium to attain equilibrium. In diffusion, the concentration is equalized throughout the medium. Now we will try to understand this process of diffusion with the help of a diagram given below
