Why does the "Whoosh Bottle" experiment behave differently at different temperatures?
In this lab, students are presented with nine unknown substances. By performing a series of tests, analyzing chemical structures, and applying their understanding of how intermolecular forces affect the properties of a substance, students will ultimately determine the identity of each unknown.
