Question

difference between diffusion and osmosis???3 points and above

Answer 1

1.Diffusion: The movement of particles or molecules from a region of higher concentration to a region of a lower concentration is called diffusion.

Examples: If a bottle filled with some gas or vapours is opened at a certain place in the room, very soon its molecules become evenly distributed throughout the available space in the room. Similarly, if a drop of ink is placed in water, it is dissolved and its particles move so that they are evenly distributed throughout the water.


2.Osmosis: The movement of water molecule through a semipermeable from the region of higher water concentration to the region of less water concentration is called osmosis. The phenomenon of osmosis can be demonstrated by the thistle funnel experiment.

Answer 2

Hey !!

DIFFUSION  

In diffusion, no semipermeable membrane is used.

In this process,the solvent as well as the solute molecules move directly into each other.

It takes place from higher concentration to lower concentration.

It takes place in gases as well as solutions.

It cannot be stopped or reversed.

OSMOSIS

In osmosis, a semipermeable membrane is used.

In this process, there is only flow of solvent molecules and that too through the semi-permeable membrane.

It takes place from lower concentration to higher concentration.

It applies to solutions only.

It can be stopped or reversed by applying pressure on the solution with higher concentration.
