2. A system is cooled at constant volume from state 1 to state 2, the internal energy decreasing 88 kJ. It is the heated from state 2 to state 3. The total work done between states 1 and 3 is 44 kJ. The system then progresses to state 4, the internal energy increasing 35 kJ. The system finally returns to its initial state, the internal energy increasing 53 kJ. Determine the heat added to the system as it changes from state 2 to state 3.
