pressure-volume
Gas law variables
Pressure-volume describes the relationship between the pressure and volume of a gas or fluid, fundamental to thermodynamics and physics.
A pressure-volume diagram plots these two variables against each other, typically showing how a gas behaves during compression or expansion.
The pressure-volume relationship is central to understanding engines, respiratory physiology, and industrial processes.
The pressure-volume curve showed the heart's pumping efficiency.
