Part B: IMFs and physical properties analysis (Outcomes 8.4, S2 and S3) • Is your substance polar or nonpolar? • What is surface tension? How is this measured? (Describe the methods in your own words.) What are the units used for surface tension? How do IMFs affect surface tension? In the grand scheme of things, does your substance have high, average, or low surface tension? What is viscosity? How is this measured? (Describe the methods in your own words). What are the units for viscosity? How do IMFs affect viscosity? Would you say your compound has high or low viscosity? • In engineering applications, when would surface tension and viscosity matter? o Is your assigned compound currently used in any engineering applications? Are there uses you can find or think of for your compound?
