How do gases help pneumatic systems do work?

Gases in pneumatic systems serve as a compressible medium that can transmit force and energy. When air or another gas is compressed, it stores potential energy, which can be released to perform work, such as moving pistons or actuating tools. The ability of gases to quickly expand and contract allows for rapid movement and precise control in various applications. Additionally, the use of gases makes pneumatic systems lightweight and efficient compared to hydraulic systems.
