Question

Explain diffusion with an example. ​

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. An example of this is the way the noxious smell of ammonia gas spreads in air.

Answer 2

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.

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
