A vertically arranged piston-cylinder assembly with a mass and area of a piston given as 55 kg and 0.011 m2, respectively is filled with 3.3 g of carbon dioxide (CO2). The initial volume and specific internal energy of the gas are 0.0048 m and 628 kJ/kg, respectively. The piston is exposed to the atmosphere and pressure of 107 kPa is exerted on the top of the piston by the atmosphere. The volume of the gas has decreased to 0.0024 m3 when 1.89 kJ heat is transferred slowly from the gas to the surrounding. (a) the pressure, in kPa, and (b) the final specific internal energy, in kJ/kg Assume: The local gravitational acceleration to be 9.81 m/s? Friction between the piston and the cylinder is neglected. Answer:
