Question

What are some examples of osmosis in real life?

Answer 1

Hint: Diffusion occurs when molecules tend to spread themselves uniformly in space, as in osmosis. Unlike diffusion, which may occur in any media (gas, liquid, or solid), osmosis occurs exclusively in liquids and (rarely) gases. Osmosis is a process in which solvents, such as water, flow across a semipermeable membrane from a lower concentration solution to a higher concentration solution. It's a passive procedure, which means it doesn't require any effort on your part.

Complete answer:
What is a semipermeable membrane, and how does it work? It's a type of barrier that permits some molecules or substances to flow through while preventing others from doing so. A plastic wrap, for example, enables water vapour and air to pass through but not food or water. Similarly, cell membranes let the passage of water and certain solutes (small molecules dissolved in a solvent) while preventing the passage of other solutes.
Osmosis attempts to bring the concentrations on both sides of the membrane into balance. Because the solute cannot pass through the membrane, the solvent must move. As the solution approaches equilibrium, it becomes more stable. As a result, osmosis favours thermodynamic rules.
Osmosis is divided into two kinds.
-When a cell is put in a solution with a greater concentration of water than the cell, the solvent flows inside the cell by endosmosis. The cell becomes turgid or undergoes plasmolysis as a result of this.
-When a cell is put in a solution with a greater concentration of solute than the cell, exosmosis occurs, and the solvent flows out of the cell. The cell becomes flaccid or undergoes plasmolysis as a result of this.
-When you keep a raisin in water and it puffs up, this is an illustration of Osmosis in everyday life.
-Movement of salt water over the cell membrane of an animal cell.
-Osmosis allows plants to extract water and minerals from their roots.
-If you spend too much time in a bathtub or in water, your finger will get pruned. The skin on your fingers absorbs water and expands.
-It's used to keep fruits and meat fresh.

Note:
In 1748, French scientist Jean-Antoine Nollet was the first to chronicle this procedure. A German scientist created extremely selective precipitation membranes more than a century later, improving the art and technology of monitoring osmotic flow.
