where the ideal gas law breaks
Controls
Presets
Real gases deviate from PV = nRT because molecules attract each other (the a term) and occupy volume (the b term). Van der Waals adds both corrections, and below the critical temperature the isotherm even loops — predicting condensation. Educational tool.

P at V=0.3 L (vdW)86.4 bar
P at V=0.3 L (ideal)88.7 bar
Deviation-3%
Governing equation
Reading this result: At 320 K the a and b corrections nearly cancel, so the real gas tracks the ideal-gas law to within 3%.
