Unformatted text preview: Experiment 2: Evaporation, Sublimation, and Intermolecular Forces Chemistry 1046L Purpose: The purpose of this lab is to explore the concepts of intermolecular forces and how different factors such as, temperature and pressure affect the forces. This lab also shows the proper construction method and use of a barometer, while also reinforcing basic measuring and calculating techniques. Furthermore, this lab demonstrates how to determine the critical point of CO . ₂ Procedure: There were no changes to the procedure. Dillon, Stephanie. “Evaporation, Sublimation and Intermolecular Forces.” CHM1046L Online Manual . Fall 2011. 21 September 2011. <http://www.chem.fsu.edu/chemlab/chm1046lmanual/forces/index.html > Data: For part II, report all of the observations made during lab of the CO 2 alone and inside your micro gauge. Report the triplet point of CO 2 found during lab. Part I: Unknowns Rank based on strength of Intermolecular force (1 strongest) Identity 1-11.5 4 Acetone 2-7.0 3 Methanol 3 0.0 1 Water 4...
