steam of mass 5 kg, contained within a piston-cylinder assembly undergoes an expansion from state 1, where the specific internal energy is u base1=2709.9 kj/kg, to state 2, where u base 2 =2659.6 kj/kg. during the process, there is heat transfer to the steam with a magnitude of 80kj. also, a pedal wheel transfers energy to the steam by working in the amount of 18.5kj. there is no significant change in the kinetic or potential energy of the steam. determine the energy transfer by work from the steam to the during the process, in kj.
