A 10 kg of steam is contained a piston-cylinder shown in the figure below, 95 kJ of heat is transferred to the steam causing it to expand from initial state where the specific internal energy is u1 = 2815 kJ/kg to final state where u2 = 2670.4 kJ/kg. During the process, a 25 kJ of paddle wheel work is also added to the steam. Assuming that there is no significant change in kinetic and potential energies, determine the work transferred by steam to the piston during the process, in kCal.
