The Second Law of Thermodynamics and Boltzmann's Statistics model performs successive simulations of an isolated assembly of vibrating molecules modeled as quantum harmonic oscillators. The objective is to reach, by means of molecular random collisions, the thermodynamic equilibrium detected through the entropy evolution and the approach to Boltzmann's distribution. When the simulation is run, each successive simulation consists of random collisions (the simulation number is indicated in the middle yellow field). The reduced entropy (S/k) evolution is displayed at the top panel after every 50 collisions as a function of the total number of collisions.
The Second Law of Thermodynamics and Boltzmann's Statistics model was developed using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the jar file will run the program if Java is installed. You can modify this simulation if you have EJS installed by right-clicking within the map and selecting "Open Ejs Model" from the pop-up menu item.
Please note that this resource requires at least version 1.6 of Java (JRE).
