Heat in the amount of 32 kJ is added to a closed system while its internal energy decreases by 23.5 kJ. a) How much energy is transferred as work? b)

For a process causing the same change of state but for which the work is zero, how much heat is transferred? Steam at 1000 kPa and 350°C enters an adiabatic turbine at a mass flow rate of 0.1 kg.s1. The exhaust from the turbine is carried is at 80 kPa and 120°C. What is the power output of the turbine? One mole of water vapor expands from 10 bar and 700 K to 1 bar by each of the following paths: (a) Constant volume (b) Constant temperature (c) Adiabatically Assuming mechanical reversibility, calculate W, Q, AU, and AH for each process.Sketch each path on a single PV diagram.
