Frequently Asked Questions
What is the ideal gas law?
The ideal gas law relates the pressure, volume, temperature, and amount of an ideal gas: PV = nRT. R is the universal gas constant (8.314 J/mol·K).
When does the ideal gas law break down?
The ideal gas law works best at low pressures and high temperatures. It breaks down at high pressures (molecules are close together), low temperatures (near liquefaction), and for gases with strong intermolecular forces.
