Question

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?

Answer 1

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!
