Quiz Yourself: Interactive Simulations
These simulations use a step-by-step procedure in which the user inputs an answer for each step and then checks the “solution box” to see the correct answer. The user then either continues to the next step or resets the simulation by selecting “new problem". Different starting conditions are created when "new problem" is selected. Most steps have a “hint” box that can be selected. These simulations are useful for thermodynamics, separations, or material and energy balances courses. They follow the format used by Bansagi and Rodgers (Education for Chemical Engineers, 22, 27-34 (2018)) in their graphic web-apps. 

Browser-Based Step-by-Step Simulations
These simulations were programmed in Javascript and will play in most browsers.

Step-by-Step Simulations
Simulations whose names are in blue will play in most browsers, but they were programmed in Mathematica, and the CDF versions, which can be downloaded, are significantly faster and can be used offline with the Wolfram CDF plug-in.
