Detailed explanation-1: -Diffusion is a type of transport that simply occurs when there is a concentration difference where the molecules move from a region of higher concentration to a region of lower concentration. When particles in liquids and gases randomly collide and disperse, diffusion takes place.
Detailed explanation-2: -Diffusion is the movement of molecules from a region of higher concentration to one of lower concentration. This movement occurs because the molecules are constantly colliding with one another. The net movement of the molecules is away from the region of high concentration to the region of low concentration.
Detailed explanation-3: -Diffusion occurs because: Molecules constantly move and collide with each other. The concentration of a solution is never the same throughout a solution.
Detailed explanation-4: -Diffusion happens because gases and liquids move from place to place in quick random motions. When this happens, the particles collide, which in turn makes them change directions. The process of diffusion occurs on its own without any help from shaking or stirring.
Detailed explanation-5: -Diffusion occurs when molecules (gas, liquid, or solid) moves from higher concentration to lower concentration. Diffusion helps in the movement of substances in and out of the cells.
