CHEM 133 LESSON 6 QUIZ | 25 QUESTIONS AND CORRECT ANSWERS (VERIFIED) LATEST UPDATE. Question 1 of 25 4.0/ 4.0 Points Of the intermolecular forces we learned about, which has the greatest strength? A. iondipole forces B. dispersion forces C. dipoledipole forces D. hydrogen bonding Feedback: London dispersion forces exist between any pair of molecules whether they are polar or nonpolar. Dipoledipole interaction exists only between polar molecules. There is a third type of van der Waals force that always accompanies dipoledipole interaction; it's called dipole induced dipole interaction. In molecules where an H atom is bonded to F, O, and N, hydrogen bonding can occur in addition to van der Waals forces. For small molecules, hydrogen bonding is significantly stronger than van der Waals forces. Question 2 of 25 4.0/ 4.0 Points We discussed many processes related to phase changes. Which of these represents the opposite of freezing? A. boiling. B. sublimation. C. none of the above D. evaporation. E. condensation. Feedback: The six phase changes: freezing, melting, condensation, vaporization, sublimation, and deposition. Question 3 of 25 4.0/ 4.0 Points As we learned, matter exists in different states: solid, liquid, and gas. Which one of these could be described as having low density and easily compressible? A. liquids B. gases C. solids D. both solids and liquids Feedback: Solids have definite shape, mass, and volume. Liquids do not have definite shape, but they do have definite mass and volume. Gases do not have definite shape or volume. Liquids and gasses will take the shape of their containers.
