Hydraulic cylinders will be linked to the bath at both ends, as the oil needs to remain pressurised to work effectively.
Pneumatic cylinders have springs if they're single way cylinders, as generally they can't rely on gravity to revert back to the first stage - dual cylinders on the other hand have 2 springs so they can switch sides.
That aside, the hissing from Pneumatics should just about give it away.

The main difference between pneumatic cylinders and hydraulic cylinders is that hydraulic cylinders?
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.
What is electro-pneumatic control?
The pneumatic system controlled by electronic systems.
When were pneumatic cylinders invented?
The first patent for the pneumatic cylinder was issued in 1940 in the US to Samuel Clegg and Jacob Selvan. Alfred Beach was given a patent in 1865 for a pneumatic subway train using a giant pneumatic tube.
What does hydraulic and pneumatic systems have incommon?
both pneumatic & hydraulic systems are applications of fluid powers
Are all air valves pneumatic?
Pneumatic is defined as air driven and therefore the two terms are synonomous. However pneumatic is not as frequently used in describing a valve.
What is the difference between pneumatic and electronics transmitter?
No difference only magnitude
What is the difference between pneumatic tires and automobile tires?
Nothing, an automobile tire is a pneumatic tire.
What is the difference of pressure between pneumatic and hidraulic?
Any pressure difference is irrelevant. The distinction is in the operating fluid. In pneumatic systems, it's a gas. In hydraulic systems, it's a liquid.
What is the difference between pneumatic and hydrostatic?
one is punomatic and one is hydromatic and that is all
What is the difference between pneumatic tools and electric tools?
It is how they are powered. Electric tools are powered by electricity and pneumatic tools are powered by forced air.
Whats the difference between the John Deere 4020 and 4030 tractors?
There is a difference between the John Deere 4020 and 4030 tractors. The differences between the two tractors include the hydrolics system. To find out more go to www.retiredtractors.com/.
What is the difference between car tires and pneumatic tires?
A tyre being pneumatic simply means that the tyre is air-filled, as opposed to solid, or filled with something else - meaning that almost all car tyres are pneumatic tyres.
Difference between hydraulics and pneumatics?
hydraulic is liquid based, pneumatic is air.
What is the difference between pneumatic elevator and hydraulic elevator?
Pneumatic elevators work on air pressure (similar to a bank's drive through suction tubes) and hydraulic elevators work on oil/water pressure.
What is the primary difference between pneumatics and hydraulics?
In hydraulics. Power is transmitted through the air. The pneumatic. Power is transferred by the oil.
On pneumatic thermostat what is the difference between direct acting and reverse acting?
A Direct Acting (DA) pneumatic thermostat increases branch line pressure as temperature increases. A Reverse Acting (RA) pneumatic thermostat decreases branch line pressure as temperature increases.
How do hydrolics work?
hydrolics work using fluid under pressure what else stupid
