a) Properties of pure substance changes with phase, temperature and pressure. It is
important to understand specific properties of a substance to evaluate its
thermodynamics properties. Given a situation where 500g of water in saturated vapor
state at 200 °C is being cooled under an isobaric condition until the enthalpy reaches
1500 kJ/kg.

Q3) A two-phase liquid-vapor mixture of water with an initial quality of 0.25 is contained in a piston
cylinder device as shown in the figure below. The mass of the piston is 40 kg, and its diameter is 10 cm.
The atmospheric pressure of the surroundings is 1 bar. The initial and final position of the piston are
shown in the figure. As the water is heated, the pressure inside the cylinder remains constant until the
piston hits the stops. Heat transfer to the water continues until its pressure is 3 bar. Friction between
the piston and the cylinderwall is negligible. Determine the total amount of heat transfer, in J.
(Gravitational acceleration g= 9.81 m/s2)
a) Draw the process in the P-V plot.
b) Calculate the heat transfered to the water until the piston hits the stops.
c) Calculate the heat required to increase the pressure of the water to 3 bar.
