Pressure associates with osmosis

Answer 1

in the context of the movement of water molecules across a semi-permeable membrane. When there is a difference in solute concentration between two sides of a membrane, water molecules will move from an area of low solute concentration to an area of high solute concentration in order to achieve equilibrium. This movement of water creates pressure, known as osmotic pressure. The greater the difference in solute concentration, the higher the osmotic pressure will be. This pressure is important for maintaining the balance of water and solutes in biological systems.
