Period 4 Ch 14 Review Game Table 1 In a glass of water, the molecules of water are kept in the glass and held to another by: Intramolecular forces, shared electrons, intermolecular forces, or ionic bonds? True or False: An intramolecular force happens within a molecule with three types of bonds: dipole-dipole, dispersion, and hydrogen bonds. Table 1 (cont.) True or false: Density is high in gas, moderate in liquid, and low in solid. The force of attraction between an atom of one molecule and its neighboring molecule: – A) Covalent Bond – B) Metallic Bond – C) Intermolecular Force Table 2 Examples of intramolecular forces are all of the following except A) Covalent B) Ionic C) Metallic D) Dispersion What is the process of changing from a solid to a gas by skipping the liquid phase A) Sublimation B) Condensation C) Heat of fusion D) Deposition Table 2 (cont.) What are the three types of intermolecular forces? What forces occur within a molecule? Outside a molecule? Table 3 1. Give one example of each. Sublimation, Vaporization, Condensation 2. what are three types of bonds in intermolecular forces? A. ionic, covalent, metallic B. ionic, hydrogen, covalent C. Hydrogen, dipole-dipole, dispersion 3. which is true about intramolecular forces and intermolecular forces A. intramolecular are in the same molecule while intermolecular forces are between neighboring molecules B. intermolecular forces have 3 types: ionic, covalent, metallic C. intramolecular forcers are weak D. intramolecular forces have strong bonds. 4. if there is more heat, will energy rise or lower over time? Table 4 1. All of these are intramolecular forces except: A) dispersion B) ionic bond C) metallic bond D) none of the above 2. Which one is a physical property for volume when heated? A) Increase gas B) Decrease liquid C) Decrease liquid Table 4 (cont.) 3. what is the change of state from gas to liquid?
