Fernández Pineda, Cristóbal ; Velasco Maíllo, Santiago | American Association of Physics Teachers | 2001-11A simple system is used to illustrate the application of different extremum principles in thermodynamics. The system consists of an ideal gas contained in an adiabatically isolated cylinder interacting with a constant-pressure work device throug[...]texto impreso
The entropy maximum principle is applied to obtain the final equilibrium state in the free expansion of a perfect gas. This provides an example where the entropy of an isolated system at equilibrium has an absolute maximum which is not a local m[...]texto impreso
A composite system consisting of two identical ideal gases separated by a movable, frictionless, diathermic piston is used to illustrate the application of different extremum principles in thermodynamics. The time evolution of the system from an[...]texto impreso
Velasco Maíllo, Santiago ; Fernández Pineda, Cristóbal | American Association of Physics Teachers | 2007-12A thermodynamic study of a pure substance at the triple point. is presented. In particular, we show that the mass fractions of the phases coexisting at the triple point obey lever rules in the specific entropy-specific volume diagram, and the re[...]
