The attached figure shows a gas contained in a vertical piston– cylinder assembly, where D = 10 cm. A vertical shaft whose cross-sectional area is 0.8 cm2 is attached to the top of the piston. The total mass of the piston and shaft is 25 kg. While the gas is slowly heated, the internal energy of the gas increases by 0.1 kJ, the potential energy of the piston–shaft combination increases by 0.2 kJ, and a force of F = 1668 N is exerted on the shaft as shown in the figure. The piston and cylinder are poor conductors, and friction between them is negligible.The local atmospheric pressure is 1 bar and g = 9.81 m/s2. (Patm = 1 bar) Determine, (a) the work done by the shaft, (b) the work done in displacing the atmosphere, and (c) the heat transfer to the gas, all in kJ.

Consider a vertical spring-loaded piston cylinder. The gas inside the cylinder has a pressure of 130 kPa. And the spring exerts a downward force of 200 N on the top of the piston. The diameter of the piston is 10 cm and the atmospheric pressure is 1 bar. Determine the mass of the piston that will maintain equilibrium. Neglect the friction effects between the surface of the piston and the cylinder.

While the piston is pinned, a cylinder with a volume of 0.05 m3 contains 200 kPa pressure and 300 K air temperature. Since the pressure is 0.4 MPa as a result of the heat transfer from the environment, the pin breaks and when the system becomes thermodynamically equilibrium, its volume becomes 0.1 m3. The area of the piston is 0.05 m2, the masses of the piston and above are 150 kg and the atmospheric pressure is 102 kPa. a) Find the temperature when the pin breaks.b) Calculate the pressure and temperature after the pin breaks and reaches the equilibrium position.
A mass of 6.7 kg of steam is contained within a piston-cylinder assembly. The steamundergoes an expansion from its initial state with e1 = 2617.6 kJ/kg to its final statewith e2 = 2506.2 kJ/kg. During the process there is a heat transfer of 72 kJ to thesteam. Also, a paddle wheel does 33 kJ of work on the steam.
