AP Chemistry Questions on Boyle's Law: Test Your Knowledge

📚 Quick Study Guide

• 🎈 Boyle's Law describes the inverse relationship between the pressure and volume of a gas at constant temperature and number of moles.
• ⚗️ The formula for Boyle's Law is: $P_1V_1 = P_2V_2$, where:
  • $P_1$ = Initial pressure
  • $V_1$ = Initial volume
  • $P_2$ = Final pressure
  • $V_2$ = Final volume
• 🌡️ Temperature and the number of moles of gas must remain constant for Boyle's Law to apply.
• 🧮 Units for pressure and volume must be consistent on both sides of the equation (e.g., both in atm or both in kPa, both in liters or both in mL).
• 💡 Remember, as pressure increases, volume decreases proportionally, and vice versa.
