Boyle's Law: Volume and Pressure
Captions available
The idea
At constant temperature, a fixed amount of gas has volume inversely proportional to its pressure.
In practice
Pushing a syringe's plunger halves the trapped gas's volume and doubles its pressure, at constant temperature.
Where people slip
Volume and pressure trade off inversely, not directly — squeezing a gas raises its pressure, never lowers it.
