Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.
Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.
Substances in solution have different van der Waals attractions for each other and they can be separated and retrieved independently by the process of distillation that uses this principle of differential "stickiness." In this activity students manipulate temperature and "stickiness" in order to model effective distillation, which is an important technique for water purification and many industrial processes.
Students will be able to:

Mass is not a factor in distillation, but if students want to be convinced that it is not, they can go to the activity Atomic Mass and Boiling Point (http://molo.concord.org/database/activities/275.html).
