What this chapter is all about…

 
 

Diffusion, osmosis, solutions, chemical reactions, electrochemistry, phase change, etc., open the world of chemistry and biology to physics. Diffusion or reactions result from the flow, the storage, and the production of substances which are driven by differences of chemical potential. Choose from biological, medical, environmental or other applications to learn about the transport and the transformation of substances.
