Briefly explain the ideal gas law and one common misconception about it.

## The Ideal Gas Law The ideal gas law is **PV = nRT**, which relates the pressure (P), volume (V), temperature (T), and amount (n) of a gas through the universal gas constant (R). It describes how these properties are interconnected—for example, if you increase temperature while keeping volume constant, pressure must increase proportionally. ## Common Misconception **Misconception**: "The ideal gas law works perfectly for all gases under all conditions." **Reality**: The ideal gas law assumes gas particles have no volume and don't attract each other, which isn't true for real gases. It works well at **high temperatures and low pressures** (when particles are far apart), but fails under extreme conditions like very high pressures or low temperatures, where real gases can deviate significantly or even liquefy. That's why we use corrections like the Van der Waals equation for real gases under non-ideal conditions.
