A PV diagram plots the change in pressure P with respect to volume V for some process or processes. Typically in thermodynamics, the set of processes forms a cycle, so that upon completion of the cycle there has been no net change in state of the system; i.e. the device returns to the starting pressure and volume.
English: A cyclic thermodynamic process described on a pressure-volume diagram. A and C are constant-pressure (isobar) evolutions, B and D are constant-volume (isochoric) evolutions. A and C are constant-pressure (isobar) evolutions, B and D are constant-volume (isochoric) evolutions.

This Process Path is a straight horizontal line from state one to state two on a P-V diagram. Figure 2. It is often valuable to calculate the work done in a process. The work done in a process is the area beneath the process path on a P-V diagram. Figure 2 If the process is isobaric, then the work done on the piston is easily calculated.

p–v–T 3D diagram for fixed amount of pure material. It is possible to envision three-dimensional (3D) graphs showing three thermodynamic quantities. [12] [13] For example, for a single component, a 3D Cartesian coordinate type graph can show temperature (T) on one axis, pressure (p) on a second axis, and specific volume (v) on a third.
A saturation dome uses the projection of a P–v–T diagram (pressure, specific volume, and temperature) onto the P–v plane. The points that create the left-hand side of the dome represent the saturated liquid states, while the points on the right-hand side represent the saturated vapor states (commonly referred to as the “dry” region).
