A closed piston-cylinder device contains 2.50 kg of water initially at 1200.0 kPa and 0.1664m3. The device is expanded to achieve a final state of 600.0 kPa and 0.9555m3. This state change will be modeled with two consecutive steps: 1) Constant volume cooling 2) Constant pressure expansion a. Calculate the overall work interaction term, W, for this state change (kJ).  b. Calculate the overall heat interaction term, Q, for this state change (kJ).  This is a review question that I have for a test, W for part a. is -473kJ and Q for part b. is 3420kJ. I am just having trouble setting them up because when I work through the problem I get a completely different answer for Q
