How to calculate the pressure / volume / temperature of gas in "connected" cylinders?

Are you sure there is a "flow" from one cylinder to the next? If so, then it would be like a hydraulic pump and you could use Pascal's Law but you would need to know forces, surface areas, and/or pressures.

It sounds like in this problem there are two separate cylinders. The first cylinder has 50L of gas and then you would decrease the pressure and increase the temperature, so you want to find what the new volume of gas woul be. If this is the case, you should use the Combined Gas Law here: P1V1/T1 = P2T2/V2 (Note that the 1's and 2's should be subscripts, not coefficients for multiplying.)

I am assuming that even though the second cylinder has a maximum volume of 1000L, which may be irrelevant, and you are just trying to find what the new volume of the gas will be. If this is the case, you would solve the above equation for V2.
