...whatever pressure it was filled to...
2,000 psig
Nitrogen slowly leaks out
Nitrogen must also have its pressure regulated before it can be used. The pressure in the cylinder is too great to be connected to a system. If a person allowed nitrogen under cylinder pressure to enter a refrigeration system, the pressure could burst some weak point in the system.

Using a pressure guage to determine the pressure of the gas inside, as thepressure decreases you can tell that it is getting empty. Another way is if you know the weight of the empty cylinder weigh the cyleinder and the difference gives you how much nitrogen is in it.
The pressure would double in size.
0.909 atm
Your question makes little sense. If a cylinder holds 6 cubic meters of nitrogen at one atmosphere pressure the volume of the cylinder is 6 cubic meters. However as 150 newtons per squsre meter = 150 Pascals = 0.001480384754 atmospheres, if you took 6 cubic meters of nitrogen at this pressure and then increased the pressure to 1 atmosphere the volue would shrink (because the volume of a gas is inversely proportional to the pressure) from 6 cubic meters to 0.008882308524 cubic meters.
The same reason every other gas in a scuba cylinder is compressed. If a cylinder is pressurized, then the gas in it is compressed by definition. If it is not pressurized, then there is obviously no gas in the cylinder to breath.
If it has a pressure between 3000 and 5000 psi and has standard threads, then yes.
