A cylinder contains 0.300 mol of an ideal gas. The cylinder has a movable piston on top, which is free to slide up and down, and which keeps the gas pressure constant. The piston's mass is 8,000 g and its circular contact area with the gas is 5.00 cm2. (a) Find the work (in J) done on the gas as the temperature of the gas is raised from 25.0°C to 310°C. J
