Henry’s law
Push a piston down on a gas above water: more gas dissolves as the pressure rises.
Open the interactive simulation →How to use this simulation
- Choose a gas.
- Move the piston (gas pressure) slider.
- Press “Record dissolved amount” at several pressures.
What to notice
- Dissolved amount is proportional to pressure: a straight line through the origin.
- CO₂ is far more soluble than O₂ or N₂.
