Hmm well if the gas is ideal then the following relation should be true:

PV=nRT

with R as the gas constant. "n" the number og moles, and P,V,T as pressure, volume and temperature.

But as for the state (p1,V1,T1), the volume will most likely be preset by the size of the container,

so once that is chosen then choosing either p1 or T1 will restrain the other one.

I mean if one were to chose p1 then the temperature will be given as T = PV/nR,

and choosing T1 the pressure will be given as p =nRT/V.

And for the rest of I can only guess unfortunately.
