Diffusion and Osmosis

Revision cards for Diffusion and Osmosis

HideShow resource information



Diffusion is the spreading of the particles of a gas, or any substance in solution, from a region where they are of higher concentration, into a region where they are in a lower concentration.

Eventually the molecules become evenly spaced into the area that they occupy.

The rate of diffusion can be increased or decreased by two variables - Heat and the difference in concentration.

Osmosis is the random movement of water molecules from a region of higher water  concentration (a dilute solution) to a region of lower water concentration (a concentrated solution) across a partially permeable membrane

This is great ...I had no idea what the difference was lol


this is so good, i was doing some notes about diffusion and this helped me a lot ;p


ahh thank youu :) x
