Material & Energy Balances Interactive Simulations

Simulations whose names are in blue will play in most browsers, but most 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-inThe QUIZ simulations follow a step-by-step procedure that requires user input.  Most simulations are also available at Wolfram Demonstration Project.
