Consider an ideal gas that occupies 1L in a cylinder with movable piston under the pressure of 10atm. if the external pressure of 10atm compresses 9atm due to nine pieces of small removable blocks of equal weights and 1atm due to atmospheric pressure, calculate the expansion workdone by the gas when: I. the nine blocks are removed from the piston at once
II. eight blocks are removed from the piston at once
III. eight blocks are removed from the piston in two batches, i. e. four blocks at a time​
