What is the difference between osmosis and defusion?

Answer 1

Osmosis is the transfer of water through a membrane to have an equilibrium of water particles on each side.

Defusion is also the transfer of water through a membrane, but because it is trying to make the concentrations of ions on each side equivilant.

Answer 2

Diffusion is the movement of any substance from an area of high concentration, to an area of low concentration.

E.g.


If you stand in the corner of a room and spray a deodorant can in the air, the air around you will have a high concentration of the deodorant, whereas the other end of he room will have no deodorant in. The deodorant will then begin to diffuse across the room (moving from the area of high concentration to the area of low concentration (the other side of the room, in this case). Eventually, the deodorant will be evenly spread throughout the room.


Osmosis is the diffusion of water through a semi permeable membrane.


A cell membrane is an example of a partially permeable membrane, and osmosis occurs in cells all the time. Osmosis keeps our cell water levels just right. When there is a low concentration of water in the cell, water diffuses into the cell. When the cell's water level is too high, water diffuses out of the cell.

Answer 3

Osmosis specifically refers to the movement of water molecules across a semipermeable membrane from an area of high water concentration to an area of low water concentration. Diffusion, on the other hand, refers to the movement of particles (solutes) from an area of high concentration to an area of low concentration, without the need for a membrane. Osmosis is a specific type of diffusion that involves water molecules.
