Mass-Elastic Band Thermodynamics: A Visual Teaching Aid at the Introductory Level William C. Galley
Demonstrations of five spontaneous isothermal processes involving the coupling of a mass and elastic band and arising from combinations of enthalpy and entropy changes are presented and then dissected. Analogies are drawn between these processes and common spontaneous molecular events such as chemical reactions and phase transitions.
