PROTEINS

• Gases


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


  Relationship between pressure and volume of a confined gas held at constant temperature - pressure and volume are inversely proportional
• Boyle's Law


  1. When volume increases, pressure decreases

  2. When volume decreases, pressure increases
• Boyle's Law equation can only be used if temperature and amount of gas are constant
• Virtual experiment


  • Observe relationship between gas pressure and volume at constant temperature and amount of gas
• • When pressure increases, volume decreases
  • When pressure decreases, volume increases
• The product of pressure and volume is constant (k) at constant temperature and amount of gas
• Applications of Boyle's Law

  • Syringe - Pressure increases, volume decreases

  Deep sea fish - Pressure decreases, volume increases

  Gas storage - Pressure increases, volume decreases

  Human breathing - Inhale - Volume increases, pressure decreases

  Exhale - Volume decreases, pressure increases

  Scuba diving - Rapid pressure decrease causes gas expansion
• Boyle's Law describes the relationship between pressure and volume of a gas at constant temperature and amount of gas
