Dissolved substance can move into and out of cells by diffusion
Diffusion is the movement of from concentration to concentration. The the difference in concentration, the faster the rate of diffusion
how if diffusion used in our body
in the lungs - oxygen passes through the cell membranes by diffusion
in the mothers placenta
in the gut, to the blood in capillary of villus in small intestine
the air into our skin
As the increases, the amount of energy available for diffusion is increased. This means that a given particle will move (there is more energy >pushing= it) at a higher temperature. Thus the will be faster as the temperature increases.
