24 Lesson 11-1-5 Learning Objectives Upon completion of Lesson 11-1-5, you should be able to: Know the difference between intra- and intermolecular forces, and the relative magnitude. Explain the differences between solids, liquids and gases at the molecular level, and relate kinetic energy and temperature to IMF strength and phase. Use melting point and boiling point data to determine relative IMF strength. Define polarizability and describe the effect of size and shape on LDFs. Identify the type of IMFs present between any species Predict IMF trends (as well as melting and boiling points) based on size, shape and polarity Chem 110: Lesson 11

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
