Neither. Pneumatic equipment uses air, under pressure, to convey mechanical energy from one place to the other. Hydraulic equipment uses water for the same reason. A hot-air balloon uses less dense hot air to fill it's balloon. Due to gravity the more dense cold air sinks down and pushes the hot air filled balloon up. The burner uses a mechanical arm with a spring (with a string and handle attached) to control the amount flame.
Yes there is. Pneumatic valve springs. They are metal bellows that have air in them. Their use is in replacing metal wire springs in a high-speed combustion engine. An example would be formula one engines.
Pneumatic, use of air. Hydraulic, use of oil or other fluid.
Pneumatic systems use air or an inert gas. Hydraulic systems use water or oil.
Difficult question to answer without context. Key thing to understand is a pneumatic system uses a compressor, whereas a hydraulic system uses a pump. Hydraulic fluid is essentially incompressible, whereas compressed air will fill any volume. Ask yourself: What is my pneumatic/hydraulic system supposed to do? How fast should it react and what horsepower is available to drive my compressor/pump? What force do I need at my actuator/motor or whatever the system is expected to power? Generally, I think pneumatic systems can react more quickly but power density is lower, so if the load is very high a hydraulic system might be better. A typical shop pneumatic system might only operate at 50psi, whereas a hydraulic system can operate at 3000psi. Finally, it's also worth thinking about system safety: if a pneumatic component fails, there will be an explosive decompression, but if a hydraulic component fails, it will leak but will not explode because hydraulic fluid does not store energy, it only transmits it.
Hydraulic , the jack uses fluid under pressure to raise the cylinder , releasing the pressure allows the cylinder to retract. Pneumatics is a similar concept using air pressure.
Transmission fluid is performed by the hydraulic system. Pneumatic power transmission system is done by the gas.
Pneumatic. Pneu = Air. Hydra = liquid
the main difference between hydraulic and pneumatic system is that hydraulics uses fluid to power their system and pneumatic uses air (in that case air is not a fluid) All matter is made up with all particles. thanks you can see more answer in this web i put these all answer.

SCUBA tanks are metal (usually steel or aluminum) that are filled with compressed air. This is loosely related to a pneumatic system.
Pneumatic, use of air. Hydraulic, use of oil or other fluid.
An air ride is a smooth ride in a vehicle resulting from an active pneumatic suspension system, rather than springs or a hydraulic system.
Pneumatic = Air! There are brake systems that use a combination of both pneumatic and hydraulic components. In those combination braking systems you would use the hydraulic brake fluid that the manufacture specifies.

Brakes that are actuated by a hydraulic fluid (such as brake fluid). Other types are air over hydraulic (air actuates hydraulics) and pneumatic (air) brakes.
