1. For a two-phase liquid-vapor mixture of water at 100°C, use tabulated property data to show that the specific Gibbs functions of the saturated liquid and saturated vapor are equal. Repeat for a two-phase liquid-vapor mixture of Refrigerant 134a at 20°C.
2. Using the Clapeyron equation, solve the following problems from Chap. 11: (a) 11.32, (b) 11.33, (c) 11.34, (d) 11.35, (e) 11.40.
3. A closed system at 20°C, 1 bar consists of a pure liquid water phase in equilibrium with a vapor phase composed of water vapor and dry air. Determine the departure, in percent, of the partial pressure of the water vapor from the saturation pressure of pure water at 20°C.
4. Derive an expression for estimating the pressure at which graphite and diamond exist in equilibrium at 25°C in terms of the specific volume, specific Gibbs function, and isothermal compressibility of each phase at 25°C, 1 atm. Discuss.
