One kilogram of water (liquid and/or vapor) at 140 kPa is contained in a piston cylinder device. The initial volume is 0.7m³ The water is then heated until its temperature reaches 700 K. The piston is free to move up or down unless it reaches a set of stops, which  piston motion. When the piston is against the stops, the cylinder volume is 1.4m³.

A. Determine the initial internal energy (kJ) of the water.

B. Determine the final internal energy (kJ) of the water.

C. Determine the work transfer (kJ) from the water.

D. Determine the heat transfer (kJ) to the water.
