**Thermodynamic Properties and Phase Diagrams**

**Objective**

Complete the list of properties (Pressure P, Temperature T, Specific Volume v, Internal Energy u, Enthalpy h, Entropy s, and Quality x) from the given data and illustrate the location of the states relative to a generic liquid-vapor saturation curve on Pressure-Volume (P-v) and Temperature-Volume (T-v) diagrams for the following cases:

**a) Water at 15 MPa, s = 2.334 kJ/K·kg**
- **P** (Pressure): 15 MPa 
- **s** (Entropy): 2.334 kJ/K·kg

**Diagram Explanation**:
- On the P-v diagram, plot the pressure 15 MPa and find the corresponding specific volume (v) using steam tables or thermodynamic charts for water.
- On the T-v diagram, determine the corresponding saturation temperature for 15 MPa and plot the point based on its specific volume and entropy.

**b) Ammonia at 32°C, h = 1089 kJ/kg**
- **T** (Temperature): 32°C
- **h** (Enthalpy): 1089 kJ/kg

**Diagram Explanation**:
- On the P-v diagram, find the saturation pressures for ammonia at 32°C and determine the specific volume using thermodynamic properties for ammonia.
- On the T-v diagram, plot the temperature 32°C and find the specific volume based on the given enthalpy and standard ammonia tables.

**c) Propane at 76°C, 800 kPa**
- **T** (Temperature): 76°C
- **P** (Pressure): 800 kPa

**Diagram Explanation**:
- On the P-v diagram, identify the saturation pressure corresponding to 76°C and map the specific volume for the given pressures using propane property data.
- On the T-v diagram, plot 76°C and find the specific volume based on the given pressure and thermodynamic properties for propane.

**Methodology**

1. **Identify the Saturation States:**
   - Use standard thermodynamic tables or charts for each substance to find the saturation temperature and pressure.
   - Mark the given state on the generic liquid-vapor saturation curve for both P-v and T-v diagrams.

2. **Calculate Missing Properties:**
   - Utilize the properties from the thermodynamic tables to find specific volume (v),
