Boyle's Law Examples: Air Compressor Explained

📚 Quick Study Guide

• 🎈 Boyle's Law describes the relationship between the pressure and volume of a gas at a constant temperature.
• 🌡️ The formula for Boyle's Law is: $P_1V_1 = P_2V_2$, where $P_1$ and $V_1$ are the initial pressure and volume, and $P_2$ and $V_2$ are the final pressure and volume.
• ⚙️ An air compressor uses Boyle's Law to compress air into a smaller volume, increasing its pressure.
• 📏 The volume and pressure are inversely proportional. If volume decreases, pressure increases, and vice versa.
• 💡 Boyle's Law assumes a closed system (no gas enters or leaves) and constant temperature.
