Introduction Molecules are constantly in motion due to thermal energy. Therefore, the molecules will move around and bump into each other. Because of this, molecules tend to spread out evenly into available space in a process called diffusion. Diffusion is the random process of molecules moving from areas of high concentration to low concentration, thus…
