Glossary

Diffusion, osmosis, chemical reactions, electrochemistry, etc., open the world of chemistry and biology to physics.

Diffusion or reaction result from the flow, the storage, and the production of substances which are driven by differences in chemical potential.

Choose from biological, medical, environmental or other applications to learn about the transport and the change of substances.
Applications
