First Law - Closed Systems Simulation
This simulation was prepared using MathematicaDownload the free CDF player, and then download the simulation CDF file (link below). Try to predict the behavior when a parameter changes before using a slider to change that parameter. For this simulation, a screencast is provided that explains how to use it.

Simulation: Temperature Changes in an Ideal Gas

An ideal gas is heated or cooled in two containers, one at constant pressure and one at constant volume. The first law and the ideal gas law are used to calculate the final temperature, T, and the changes of internal energy and enthalpy for each system. The work is calculated for the constant-pressure process, and the final pressure is calculated for the constant-volume process.

Try to answer these questions before manipulating the simulation:

1. Which will produce more work when heated, a constant-pressure or constant-volume process?
2. Which ends at a lower temperature when cooled, a constant-pressure or constant-volume process?
