Lecture
This lecture explores two applications of osmosis: one in biological phenomena, such as the importance of osmosis in biological systems due to semi-permeable membranes, and another in practical use, specifically in desalination processes. The instructor first summarizes the previous module on osmosis, discussing the calculation of osmotic pressure and the equilibrium in osmotic systems. Then, two simple examples are presented to illustrate the concepts discussed. The first example focuses on the importance of osmotic pressure in biological systems, while the second example demonstrates the practical application of osmosis in desalination, where applying pressure on the solvent side forces water through a semi-permeable membrane, leaving behind salt.
