Topic 6: Transport

Diffusion

Due to random motion of molecules, molecules will have net movement from high concentration areas to low concentration areas

Individual molecule movement

Individual molecule movement is random but net movement as a whole can have a direction

Equallibrium

Diffusion will eventually cause an even distribution over time. When everything is balanced, we will have equilibrium.

Movement at equilibrium

At equilibrium, movement does not stop, but the movement is balanced

Osmosis

A special case of diffusion that details the movement of water across a semi-permeable membrane
