1. The problem statement, all variables and given/known data Calculate the work done when the volume of a cylinder is increased by 90.0 L against the atmospheric pressure. Think about the upward movement of a piston as it expands the volume of a cylinder. --- I am actually an AP Chemistry student and am supposed to do this problem using unit analysis as I am not taking AP Physics. However, I have taken Grade 11 Physics. Thank you for your help! -- My Work: Since 1 L = 0.001 m3, then 90.0 L = 0.0900 m3. Since 1 Pa = 1 N/m2, then 1.013E5 Pa = 1.013E5 N/m2. In order to get Nm = J = work: 1.013E5 N/m2 x 0.0900 m3 = 9,117 Nm = 9117 J = 9.12 x 103 J.
