BOYLE'S LAW

• Gases


  Made up of molecules with random and scattered arrangement due to very weak intermolecular forces of attraction
• Boyle's Law


  1. Pressure and volume of a confined gas held at constant temperature are inversely proportional

  2. When one doubles, the other is reduced by half
• As volume increases


  Pressure of the gas decreases
• As volume decreases


  Pressure of the gas increases
• Boyle's Law equation can only be used if temperature and amount of gas are constant
• Applications of Boyle's Law

  • Syringe - Pressure increases and volume decreases when plunger is pushed
  • Deep sea fish - Pressure decreases dramatically when brought to surface, causing gases in blood and swim bladder to expand
  • Gas storage - Gases are highly pressurized to reduce volume
  • Human breathing - Inhale - volume increases, pressure decreases; Exhale - volume decreases, pressure increases
  • Scuba diving - Dissolved gases in blood expand and form bubbles if surfaced too quickly
• Boyle's Law describes the relationship between pressure and volume of a gas at constant temperature and fixed amount
