  • Example 3: A vertical piston-cylinder assembly (see figure) contains 10 L of air at 20oC. The cylinder has an internal diameter of 20 cm. The piston is 2 cm thick and is made of steel of density 7830 kg/m3 . If the atmospheric pressure outside is 101 kPa, (a) determine the pressure of air inside the cylinder. The air is now heated until its volume doubles. (a) Determine the boundary work transfer during the process. (b) How would the answers change if the piston weight was neglected?
