An illustration of thermodynamic vaporization of water in a cylinder with piston. The cylinder filled with water is heated, and gradually turns into the vapor. As the water is heated, the piston moves up the cylinder. Cylinder B is saturated vapor, system with vapor and liquid, while the cylinder C is superheated vapor, containing only gas.

A piston system from a quadruple expansion engine showing the movement of steam. Steam first enters the first piston, then expanded into the first intermediate piston. This pushes the piston down, then the steam enters the second intermediate to push the piston up. The steam then enters the low piston, where the steam exits the system.
