Is the number of moles of a substance contained in a system an extensive or intensive property?
Five kilograms of water at 35 degrees Celsius are placed in a piston under 5.335MPa (State 1). Heat is added to the water at constant pressure until the piston reaches a stop at a total volume of 0.035 m3 (State 2). Most heat is added at constant volume until the temperature of water reaches 322 degrees Celsius (State 3). Determine (a) the quality of fluid and the mass of the vapor at State 2, and (b) the pressure of the fluid at State 3.

Arigid tank contains saturated liquid and vapor mixture of Refrigerant-134a at 26 °C. The volume of
the tank is 1.8 m and heat is transferred until the refrigerant is saturated vapor at 48 °C. Determine
the mass of vapor present at the initial state, in kg.
