An ideal gas in a container with a piston is taken through a two-step process. In the initial step, volume is kept constant at 0.800 m3 as the pressure is raised from 0.980 × 105 Pa to 4.20 × 105 Pa. In the subsequent step, the gas is compressed, keeping the pressure constant at 4.20 × 105 Pa to a final volume of 0.450 m3. What is the total work done during this two-step process?
