Gas Law

• Gas Laws

  • Boyle's Law
  • Charles' Law
  • Gay-Lussac Law
  • Avogadro's Law
  • Ideal Gas Law
• Charles' Law


  At constant P, as the volume increases, the temperature also increases
• Boyle's Law


  At constant T, if pressure increases, then volume decreases
• Gay-Lussac Law


  At constant V, as pressure increases, the temperature also increases
• Avogadro's Law


  When the amount of gas increases, the volume of the gas also increases
• The gas laws were developed

  End of the 18th century
• Boyle's Law

  It provides a relationship between the pressure and the volume of a gas
• Charles's Law

  It provides a relationship between the volume occupied by a gas and the absolute temperature
• Gay-Lussac's Law

  It provides a relationship between the pressure exerted by a gas on the walls of its container and the absolute temperature associated with the gas
• Avogadro's Law

  It provides a relationship between the volume occupied by a gas and the amount of gaseous substance
• The Combined Gas Law (or the Ideal Gas Law)


  It can be obtained by combining the four laws listed above
