If given a device to lift a large mass, would you use a hydraulic/pneumatic fluid?

1. The problem statement, all variables and given/known data
Right now, im learning fluids and this question is just asking if i should use either hydraulic or pneumatic fluid for a device that will be able to lift a large fluid.


2. Relevant equations
For pneumatic systems, flow rate is most often expressed as standard cubic feet per minute (SCFM) or normal liters per minute (nL/min)


3. The attempt at a solution
well i know hydraulic uses oil and pneumatic uses air. I think air is used to lift things up but i think pneumatic is stronger.

What is large fluid? Do you mean just large mass?

Think about compressibility of gases and liquids.
