A thermally insulated piston divides a nonconducting container in two compartements, right compartement of `2V, T` and `2P`, while in the left compartement the respective values are `V, T` and `P`. Total moles in total system of both comartments is `5` moles. if piston can slide freely, and in the final equilibrium position, volume of right compartement is `(xV)/(5)` then find the value of `x`.
