It depends on the process path. If you assume it is a constant pressure process, then the boundary work is just [itex]W_b = P(V_2 - V_1)[/itex].

You integrate the pressure with respect to volume. Depending on the process (isobaric, isochoric, isothermal, isentropic) this function (p = f(v)) will be different. These functions can be derived using the ideal gas law.
