Explain the diffusion in all types of matter and explain the reason with a suitable example.
Answers
Diffusion is the process of movement of molecules under a concentration gradient. It is an important process occurring in all living beings. Diffusion helps in the movement of substances in and out of the cells. The molecules move from a region of higher concentration to a region of lower concentration until the concentration becomes equal throughout.
Liquid and gases undergo diffusion as the molecules are able to move randomly.
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.
hope it helps you
Diffusion refers to the movement of particles from an area of high concentration to an area of low concentration. For example, the smell of hot sizzling food from the kitchen reaches us in the other room because the the particles of the aroma diffuses into the air dues to kinetic energy caused by heat
thnx a lot for giving me a tonne of thanks
