Submit your document with data table, graph, and questions responses below. 1. Create a graph of your data. Remember to include a title, axis labels, and units.
2. Does water or rubbing alcohol have a higher surface tension? Why do you think this?
3. Using the internet, look up the surface tensions of water and isopropyl alcohol. Were you correct?
4. Identify all the intermolecular forces that are interacting within water molecules.
5. What type of intramolecular bonding does a water molecule have?
6. Identify all the intermolecular forces that are interacting within rubbing alcohol molecules.
7. What type of intramolecular bonding does an alcohol molecule have?
8. Compare and contrast the intermolecular and intramolecular forces of water and isopropyl alcohol. How do the
properties resulting from those forces explain the differences in surface tension observed in the experiment?
9. Describe the polarity of water and isopropyl alcohol molecules and how this affects surface tension,
10. How did this experiment illustrate the concept of intermolecular forces and surface tension?
