Explore gas pressure, volume, and temperature
Change one quantity, watch its partner respond, and keep the required conditions fixed.

- Boyle: change volume while n and T stay fixed. Pressure varies inversely with volume.
- Charles: change absolute temperature while n and P stay fixed. Volume varies directly with temperature.
- Pressure–temperature: change absolute temperature while n and V stay fixed. Pressure varies directly with temperature.
- Avogadro: change amount while P and T stay fixed. Volume varies directly with amount. The particle icons represent relative amount, not a literal count of molecules.
About this model. The values obey the ideal gas law; real gases can deviate, especially near condensation or at high pressure. Particle paths, collisions, sizes, and wall speed are qualitative illustrations, not a molecular dynamics calculation.
