Key Concepts: Gay-Lussac's Law

Core Definitions

• Gay-Lussac's Law: At constant volume, pressure and temperature are directly proportional: P₁/T₁ = P₂/T₂.
• Direct Relationship: As temperature increases, pressure increases (and vice versa).
• Constant Volume: Applies to rigid containers where volume cannot change.
• Temperature in Kelvin: Always use Kelvin for gas law calculations.
• Example: A tire's pressure increases on a hot day (same volume, higher temperature).
• Pressure Cooker: Sealed container: increasing temperature raises pressure, cooking food faster.
