Diffusion is the movement of molecules from an area of higher concentration to area of lower concentration.
Explanation: Diffusion is a type of passive transport in which molecules moves from a region of higher concentration to the region of lower concentration. In passive transport, molecules moves from one place to another place without the use of energy.
For example, if a person spray perfume in one corner of the room after sometime the scent of perfume will be smelled in other corner due to diffusion.
Diffusion is the process or a spontaneous movement of particles from an area of higher concentration to an area of lower concentration.
Examples are;
1. perfume
2. A drop of ink in a cup of water.
From these two examples when it is dropped, especially ink, it diffused inside the entire space of the cup and fill all the space by penetrating the entire molecule of the water available.
