Question

what is deffuision
and give two example.of it​

Answer 1

Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. The material that diffuses could be a solid, liquid or gas. Similarly, the medium in which diffusion occurs could also be in one of the three physical states.

OR

Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.

Example:

Take water in a beaker. Add a few copper sulfate crystals at one place and leave it as it is for some time without disturbing it. After some time we can see that beaker contains a uniformly coloured solution. Here, both water and copper sulfate diffuse independently. With this experiment, we can infer that solutes move from a higher concentration to the lower concentration in a solution.

Answer 2

Answer:

Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells.  Example are :-

1. This is the way the noxious smell of ammonia gas spreads in air.

2.A few crystals of potassium permanganate in water will diffuse and turn the water purple.
