Gases

• Ideal gas equation

  PV = nRT, where P is pressure, V is volume, n is the number of moles, T is temperature, and R is the ideal gas constant (0.0821 L-atm/mol K)
• In gas laws, temperatures must be measured in Kelvin
• Gas laws

  • Boyle's law
  • Charles' law
  • Gay-Lussac's law
  • Avogadro's law
  • Combined gas law
  • Law of partial pressures
  • Law of effusion
• Boyle's Law


  A particular amount of gas at a constant temperature increase in volume when the pressure is decreased
• Charles Law


  A particular amount of gas in a constant pressure increase in volume when the temperature is increased
• Gay-Lussac's Law


  A particular amount of gas in a constant volume increase in temperature when the pressure is increased
• Avogadro's Law


  A gas in a constant pressure and temperature increases in volume when the number of particles is increased
• Law of Partial Pressures


  The pressure of a mixture of gases is the sum of the pressures of the individual components
• Law of Effusion


  The rate at which a gas diffuses is inversely proportional to the root of its density (or mass)
