Calculating and Visualizing Thermodynamic Equilibrium: A Tutorial on the Isolated System with an Internal Adiabatic Piston
Ferreira, Joao Paulo M.
Journal of Chemical Education, v84 n11 p1834-1839 Nov 2007
The problem of the equilibrium state of an isolated composite system with a movable internal adiabatic wall is a recurrent one in the literature. Classical equilibrium thermodynamics is unable to predict the equilibrium state, unless supplemented with information about the process taking place. This conclusion is clearly demonstrated in this article. In addition, some simple methods for estimating the constrained equilibrium point are proposed. These methods are accessible to first- or second-year college students; they provide physical insights, and constitute a good practice of basic principles and relations of thermodynamics. (Contains 1 figure and 3 tables.)
