Consider nitrogen gas contained in a piston-cylinder arrangement. The cylinder diameter is 150 mm. At the initial state the temperature of the N2 is 500 K, the pressure is 100 kPa, and the height of the gas column within the cylinder is 200 mm. Heat is removed from the N2 by a quasi-static, constant-pressure process until the temperature of the N2 is 300 K. Calculate the work done by the N2 gas.
