Look at problem 4a again. The contents of the cylinder are replaced now with 3.25 moles of an ideal gas. Let the external pressure change very, very slowly so that the piston moves into the cylinder 42.5 cm - this compression is reversible. The temperature is held constant at 292 K. The initial volume is 2.00 m3. Find the work done on the system. Make sure to show units and the correct number of significant figures
