“Thermodynamics: Four Laws That Move the Universe” S:1 E:21 The Electrochemical Potential

S:1 E:21 The Electrochemical Potential Use a classic science fair project – the potato battery – to trace the source of the electron flow that makes batteries so indispensable to modern life. In the process, learn about the electrochemical potential, which describes the underlying thermodynamics of any system in which chemical reactions are occurring together with charged particles.
