In chimica fisica, fenomeno di diffusione tra due liquidi miscibili attraverso una membrana di separazione, che può essere provocato da cause di natura termica (termoosmosi), elettrica (elettroosmosi) o, nel caso più comune, da una differenza di concentrazione tra due soluzioni di uguali componenti o tra una soluzione ...

What are some examples of osmosis in real life?
- The real-life examples of osmosis are: Feeling thirsty after having salty food. Dialysis of kidney in the excretory system. Swelling of resins and other seeds when they are soaked in water. Movement of salt-water in the animal cell across our cell membrane. Movement of water and minerals from root nodules to various parts of plants.
What is osmosis and why does it occur?
- Osmosis occurs because dissolved particles have a higher concentration on one side of a membrane, that only allows the passage of water, than the other. As water molecules randomly drift across the membrane, they tend to stay around the dissolved particles rather than drifting back.
What are the different types of osmosis?
- The three types of osmotic conditions that affect living cells are called hypertonic, hypotonic, and isotonic states. These terms describe the osmotic state of the solution that surrounds a cell, not the solution inside the cell. Hypertonic conditions cause water to diffuse out of the cell, making the cell shrivel.
What is an example of osmosis in everyday life?
- Some examples of Osmosis in everyday life are:- when you keep raisin in water and the raisin gets puffed. Movement of salt-water in animal cell across our cell membrane. Plants take water and mineral from roots with the help of Osmosis. If you are there in a bath tub or in water for long your finger gets pruned.
