How do you find the pressure in a container if you don't have the temperature? 

Like if we are given the pressure and container size and then asked what the pressure would be in a different container size how would I find it?

Is there an equation to solve these types of problems?

It depends on the process.
Like for example if the process is isothermal(temperature is constant), you can use,
PV = constant or P1V1 = P2V2 where P1V1 are initial conditions and P2V2 are final.


For adiabatic process,

PV^gamma = constant or P1V1 ^gamma = P2V2 ^gamma.

where gamma = Cp
------
Cv
Cp = specific heat at constant pressure and Cv = specific at constant volume.

Value of Gamma will be given in question.
Hope this helps!
