An insulated, vertical piston–cylinder device is purchased from a manufacturer. Upon purchase, it contains 3 kg of water at precisely 20 degrees celcius. The mass of the piston is such that it maintains a constant pressure of 300 kPa inside the cylinder. Liquid water at 2 MPA and 873.15 Kelvin is allowed to enter the cylinder from a supply line until the instant that the last drop of liquid in the cylinder vaporizes (saturated vapor). Find the mass of the steam that has entered [kg].
3) In a fixed volume container with a volume of 0.1 m^3, initially there is saturated water vapor at 130°C. The vessel is connected to a pipe through which steam flows through a valve at 2 MPa pressure and 350°C temperature. Then the valve opens and steam enters the container. Meanwhile, the temperature of the steam in the container remains constant at 130°C due to the heat transfer to the environment. When it is observed that 3/4 of the water in the container covers the liquid phase by mass, the valve is closed. Calculate a) the final pressure in the container, b) the mass of steam entering the container, c) the heat transfer to the environment.

A piston cylinder contains 1.25 kg water at 25°C with a constant load on the piston such that the pressure is 300 kPa. A nozzle in a line to the cylinder is opened to enable flow to the outside atmosphere at 100 kPa and 25°C. The process continues until 85% of the initial mass has flowed out.
