📚 Quick Study Guide

  • 🌡️ Gay-Lussac's Law describes the relationship between pressure and temperature of a gas at constant volume and mass.
  • 📝 The formula is expressed as: $P_1/T_1 = P_2/T_2$, where P is pressure and T is temperature (in Kelvin).
  • 🧊 Temperature must be in Kelvin (K). To convert Celsius (°C) to Kelvin (K): $K = °C + 273.15$.
  • 💡 Real-world examples include pressure changes in a car tire on a hot day or an aerosol can left in the sun.
  • ⚠️ The law assumes ideal gas behavior and constant volume.
