Define a diffusion?

1.	Define a diffusion?
Answer» Diffusion is the process in which the molecules of a matter get uniformly mixed with another matter The process of intermixing of two different typees of matter on their ownn. Diffusion is the process in which molecules like gases move from the region of its high concentration to the region of its low concentration The movement of gases (like carbon dioxide and oxygen) from a region of high concentration to a region of low concentration through a semi permeable membrane is known as diffusion. Thus, diffusion plays an important role in gaseous exchange between the cells as well as the cell and its external environment. The spreading and intermixing of particles of matter due to its motion is called diffusion
