Unit 6: Particle Interactions & Gases

Unit Objectives:  At the completion of this Particle Interactions & Gases unit,

1. I can predict, using the shape of a molecule and the polarity of bonds in a molecule, the type of intermolecular forces (hydrogen, dipole-dipole, London dispersion forces) for a given compound. (CK12 Sections 9.12, 9.17, 9.18)

2. I can justify the relative strength of attractive forces existing between particles in the various states of matter. (CK12 Section 9.20)

3. I can construct and analyze heating/cooling curves, identifying states of matter, phase changes, energies present, melting/freezing points, and boiling/condensing points. (CK12 Sections 13.17, 13.18, 13.7, 13.9, 13.11, 13.12)

4. I can differentiate between endothermic and exothermic reactions and processes. (CK12 Section 17.5)

5. I can calculate the amount of heat gained or lost as a substance is heated and/or cooled. (CK12 Sections 17.6, 17.7, 17.9, 17.12, 17.13, 17.14)

6. I can explain how the Kinetic Molecular Theory describes the behavior of gases (diffusion, effusion, compressibility, expansion, fluidity, low density). (CK12 Sections 13.1, 13.2, 13.3, 13.4, 14.1)

7. I can explain the relationship between temperature and average kinetic energy and justify why the Kelvin temperature scale is used to describe gases. (CK12 Section 13.5)

8. I can convert temperature readings in Celsius to Kelvin and vice versa. (CK12 Section 13.5)

9. I can identify real gases that behave like ideal gases under specific conditions. (CK12 Section 14.11)

10. I can explain the relationship between the pressure, volume, and temperature of a gas (Boyle’s, Charles’, & Gay-Lussac’s Laws), supported by the kinetic molecular theory. (CK12 Sections 14.3, 14.4, 14.5, 14.6, 14.7, 14.8, 14.9)

11. I can perform stoichiometric calculations given data about gases. (CK12 Sections 14.10, 12.5)

12. I can perform calculations using the combined and ideal gas laws to solve for pressure, volume, temperature, the number of moles of a gas, density, and molar mass. (CK12 Section 14.14)

13. I can explain Dalton’s Law of Partial Pressures and be able to calculate partial pressures. (CK12 Sections 14.12, 14.13, 14.14)

14. I can explain Graham’s Law of Effusion and justify with calculations. (CK12 Section 14.15)
