Strictly speaking, which is better depends on the equipment of which this cylinder is a part of. Pneumatic systems take on slight change in volumes (as air can get compressed on load and reduce in volume) and hence, a big NO for systems where even minute linear movements are critical. Hydraulic systems offer exact displacements. There are other considerations too
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.
It depends on the dam. Some dams are hydraulic and some are pneumatic. Short answer: Both
Pneumatic systems use air or an inert gas. Hydraulic systems use water or oil.
no its pneumatic.
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.
Yes. Though the response time of a pneumatic system is better as compared to hydraulic, power output is higher in latter.

Single-acting devices consist of a large plunger, or piston, into which oil (or air in a pneumatic cylinder) is pumped.
both pneumatic & hydraulic systems are applications of fluid powers
its hydraulic.
It depends on the dam. Some dams are hydraulic and some are pneumatic. Short answer: Both
both, if it pumps liquid then it's hydraulic, if it pumps gas it is pneumatic
Hydraulic cylinder use a liquid medium, often some type of viscous oil, in the cylinders and can be subject to higher pressures then pneumatic cylinders which use air or some other gas and work under a lower pressure.
It may be hydraulic or pneumatic system
Pneumatic. Pneu = Air. Hydra = liquid
Transmission fluid is performed by the hydraulic system. Pneumatic power transmission system is done by the gas.
They are hydraulic. Most controls surfaces are hydraulic.
