Required information
Water initially at 200 kPa and 300°C is contained in a piston-cylinder device fitted with stops. The water is allowed to cool
at constant pressure until it exists as a saturated vapor and the piston rests on the stops. Then the water continues to cool
until the pressure is 100 kPa.
NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
Water
200 kPa
300°C
On the T-V diagram, sketch, with respect to the saturation lines, the process curves passing through the initial, intermediate, and final states of the water. Label the
T, P, and V values for end states on the process curves.

A piston-cylinder device contains 0.87 kg of refrigerant-134a at -10°C. The piston that is free to move has a mass of 12 kg
and a diameter of 25 cm. The local atmospheric pressure is 88 kPa. Now, heat is transferred to refrigerant-134a until the
temperature is 15°C. Use data from the tables.
R-134a
-10°C
Determine the change in the volume of the cylinder of the refrigerant-134a if the specific volume and enthalpy of R-134a at the initial
state of 90.4 kPa and -10°C and at the final state of 90.4 kPa and 15°C are as follows:
= 0.2418 m³/kg, h₁ = 247.77 kJ/kg
3
v2 = 0.2670 m³/kg, and h₂ = 268.18 kJ/kg
The change in the volume of the cylinder is
