Unit 5: The Properties of Gases

Topics:

• kinetic molecular theory and the explanation of gas behavior
• pressure/atmospheric pressure
• measuring pressure - barometer/manometers
• absolute temperature scale/STP conditions
• the relationships among the 4 variables (P, V, T, and n) that effect gas behavior: Boyle's, Charles', Gay-Lussac's, and Avogadro's Principle
• ideal vs. real gases
• derivation and use of the ideal gas law equation
• calculation and use of the universal gas constant (R)
• stoichiometry of chemical reactions involving gases
• Graham's Law of Diffusion
• Dalton's Law of Partial Pressures
• experimental technique of collecting gases "over water"
