what is diffusion explain it briefly
Answers
Answer:
Diffusion is the process wherein the molecules merge as a result of their kinetic energy of random motion. It occurs in liquids and gases because their molecules move randomly. The molecules move from a region of higher concentration to a region of lower concentration, down the concentration gradient, until the concentration equalizes throughout the medium.
types of diffusion
a) simple diffusion
b)facilitated diffusion
Examples of Diffusion
A teabag immersed in a cup of hot water will diffuse into the water and change its colour.
