The Pressure Law

• The Pressure Law

  • When gas volume is constant, it adheres to the pressure law.
  • States that pressure (P) is proportional to the temperature (T)
  • As the pressure increases, so does the temperature (and vice versa)
  • P ∝ T --> Abbreviation of the pressure law

  P₁/T₁ = P₂/T₂ P₁ = Initial Pressure (kPa)

  T₁ = Initial Temperature (K)

  P₂ = Final Pressure (kPa)

  T₂ = Final Temperature (K)
• Boyle's Law

  • States that pressure is inversely proportional to volume of gas
  • As the pressure increases, the gas volume decreases
  • P ∝ 1/V --> Abbreviation of Boyle's Law

  P₁V₁ = P₁V₂ P₁ = Initial Pressure (kPa)

  V₁ = Initial Volume (cm³)

  P₂ = Final Pressure (kPa)

  V₂ = Final Volume (cm³)
