Gcse science revision - diffusion of gases diffusion and the velocity of a gas skittles colour diffusion experiment - duration:.

Rate of diffusion is influenced by several factors including temperature, concentration difference and particle size the diffusion rate is also affected when there is a change in distance between the points where diffusion occurs diffusion is the movement of atoms or particles from an area of high. Diffusion through a cell membrane introduction: substances, such as water, ions, and molecules needed for cellular processes, can enter and leave cells by a passive. Diffusion occurs in all states of matter: solid, liquid, and gas it occurs rapidly enough to be observable in a reasonable period of time. Diffusion is the movement of a substance from a region of higher concentrationto a region of lower concentration diffusion is the movement of gas or solute molecules from a region of higher concentration to a region of lower concentration until they are equal.
