Behavior of Gases Study Guide
“It’s a gas, gas, gas!” ~ Rolling Stones
Unit Test: Tuesday 5/6/14
Essential Questions:
· What factors affect gas pressure?
· Why are gases easier to compress than solids or liquids?
· How are temperature, volume, and pressure of a gas related?
· Under what conditions are real gases most likely to differ from ideal gases?
· How is the total pressure of a mixture of gases related to the partial pressures of the component gases?
· How does the molar mass of a gas affect the rate at which the gas effuses or diffuses?
Vocabulary: Must know vocabulary!
Avogadro’s hypothesis ideal gas law ideal gas constant
Boyle’s law Kelvin temperature ideal gas
Charles’ law kinetic energy real gas
combined gas law kinetic theory partial pressure
Dalton’s law of partial pressures mole fraction
Gay-Lussac’s law standard temperature and pressure (STP)
Formulas:
1 atm = 760 mm Hg = 101.3 kPa
Kelvin = °C + 273
Boyle’s Law: P1 * V1 = P2 * V2
Charles’s Law: V1T1= V2T2
Gay Lussac’s Law: P1T1= P2T2
Combined Gas Law: P1 * V1T1= P2 * V2T2
Ideal Gas Law: PV = nRT R = 8.31 (L*kPa)/(K*mol)
Dalton’s Law: Ptotal = P1 + P2 + P3 + …
