100 L of water at 50°C and 250 kPa is contained in a piston-cylinder device. Heat is transferred to the water while maintaining the pressure constant until all the liquid is evaporated. Measurements show that during this evolution, the change in enthalpy of the fluid is equal to the heat exchanged with the environment. (compressed liquid properties may be approximated as saturated liquid if needed) a) Calculate the mass of water. (10 pts.) b) Determine the total enthalpy change, AH. (15 pts.) c) Calculate the work exchanged, and interpret its sign. (15 pts.) d) Show the process on a T-v diagram with respect to saturation lines. (10 pts.)
