1. (10 pts) A frictionless piston-and-cylinder device contains 10kg of water initially at 200C and 0.2MPa. The piston is then pushed slowly in an isothermal process until the volume of water becomes 11% of its initial value. Calculate the heat and work exchanged between the device and the surroundings during this process. Hint: Use Appendix A.III and Lever rule to calculate vapor mass fraction (from specific volume data), final specific entropy, and final specific internal energy
