Which description describes pneumatic energy?

Which description describes pneumatic energy?

• A. Air under pressure.
• B. Liquid under pressure.
• C. Electric current.
• D. Thermal energy.

Answer: (A)

Pneumatic energy is the energy stored in compressed air. When air is pressurized, it holds potential energy that can be released to move pistons, operate actuators, or power tools, turning that stored energy into motion and work. This distinguishes it from other forms: a liquid under pressure describes hydraulic energy, electric current is electrical energy, and thermal energy relates to heat. Pneumatic systems rely on the compressibility of air and are valued for quick, simple actuation, even though they may deliver lower force compared to hydraulics.
