A piston/cylinder arrangement with an cross sectional area of 1 mạ contains carbon dioxide at 200 kPa and 290 K. The cylinder has a thick piston that initially held by a pin as shown in Figure 1. The metal piston has a density of 8000 kg/mº, standard acceleration of gravity, &c is 9.81 m/s and the atmospheric pressure is 101 kPa. The pin is now removed, allowing the piston to move and after a while the gas returns to 290...
