Gaseous is CO2 is contained in a vertical piston cylinder assembly by a piston with mass 50kg and having a face area of 0.01m² The mass of the CO2 is 55 grams. The CO2 is initially occupies a volume of 0.005m³ and has the change in internal energy of AU = 0.68 */kg- The atmosphere exerts a pressure of 94kPa on the top of the piston. Heat transfer occurs slowly from the CO2 to the surrounding, and the volume of the CO, decreases to 0.003m³. Friction between the piston and the cylinder wall can be neglected. The changing kinetic and potential energy of gas is negligible. The kinetics energy of piston can be ignored but the potential energy should be taken into consideration. The local acceleration of gravity is 9.75 m/s² Consider the piston and gas together as a system in the cylinder, calculate the following: A. What is the change in internal energy of CO2 gas in kJ? B. What is the change in internal energy of piston in kJ? C. What is the change in potential energy D. What is the work in kJ? of piston in kJ? E. What is the amount of released heat in kJ?
