Final answer:
To calculate thermodynamic properties in the saturated liquid-vapor mixture region, the Clausius-Clapeyron equation is used to relate vapor pressure and temperature, which can determine the enthalpy of vaporization.
Step-by-step explanation:
To calculate thermodynamic properties in the saturated liquid-vapor mixture region, one often uses the Clausius-Clapeyron equation. This equation relates the change in vapor pressure with temperature for a substance undergoing phase change. The Clausius-Clapeyron equation is given by P = Ae-ΔHvap/RT, where P is the vapor pressure, A is a constant, ΔHvap is the enthalpy of vaporization, R is the gas constant, and T is the temperature in Kelvin. By measuring vapor pressure at two different temperatures and using these values, one can calculate the enthalpy of vaporization. The enthalpy of vaporization can then be used to calculate properties such as the temperature at different vapor pressures or vice versa.
