Frequently Asked Questions
What is the ideal gas constant?
The ideal gas constant R has the value 8.314 J/(mol·K) or 0.08206 L·atm/(mol·K). It relates pressure, volume, temperature, and amount of an ideal gas through PV = nRT.
When does the ideal gas law fail?
The ideal gas law is inaccurate at very high pressures, very low temperatures, or for gases with strong intermolecular forces. In these cases, the van der Waals equation or other real gas equations are used.
