A closed system receives 175 kJ of energy by the work mode and 125 kJ by the heat mode. It is now required to return the system to its
original state by an adiabatic process.
Which of the following processes will do this?
O a.
O b.
O C.
O d.
O e.
Doing nothing. The original processes have already returned the system to its original state.
Adding 300 kJ of energy by the work mode
Removing 300 kJ of energy by the heat mode
Removing 300 kJ of energy by the work mode
Adding 300 kJ of energy by the heat mode
