Extracted text: A piston cylinder assembly contains steam. Initially, the specific internal energy (internal energy per unit mass) is equal to 2600 kJ/kg. The steam undergoes a process during which 90 kJ of heat is transferred to the steam. On the other hand, using a specific mechanism installed in the cylinder, 20 kJ of energy are transferred to the steam by work. If 10 kJ of heat is dissipated from the steam to the outside of the cylinder through the wall of the cylinder, Determine the work done by the steam on the piston. The specific internal energy at the final state is equal to 2500 kJ/kg. The mass of the steam is 4.4 kg. Select one: a. 1211 kJ b. 540 kJ c. 780 kJ d. 328 kJ
