5. Below you find a sketch of the p,T-phase diagram of H20, indicating preferred physical states of H20 at different temperatures and pressure. The regions labeled with In, XI, and III, stand for different forms of solid H20. For example, ice Ih is the standard ice (there are more than 12 different forms of solid H2O). Draw two diagrams for the chemical potentials as a function of temperature (from Ti to T2) of each of the phases (there are 5...

Note: you need to have saturate line in your diagram and please write the numerical values of the initial state and final state on your diagram (a) T v diagram; water at the iniial state of 32 MPa and 30 C undergoesa (b) P- v diagram; water at the initial state of 2.5 bar and 0.6 quality...
4. Show that two phases are in thermal equilibrium only if the temperatures are the same (volume is constant) and that they are in mechanical equilibrium only if their pressures are equal (temperature and total volume is constant). For the first part, note that ds = 0. In addition, S is additive between two phases that can be written as a function of U and V. Use the fact that dV is equal to zero. For the second part, add...
// Chemical potential/phases A substance has three phases: gas, liquid, and solid. The chemical potentials of various phases are illustrated below. T (K) 1) For a given temperature, which of the states represents an equilibrium condition? Submit 2) If the substance starts out in state Q and is held at constant temperature, what happens if it is allowed to reach equilibrium? The substance will freeze. The substance will evaporate The substance will melt and evaporate. The substance will sublime. Nothing...
only 6...7...and 8 The Gibbs function of a thermodynamic system is defined by G H- TS. If the system is consisting of two phases 1 and 2 of a single substance and maintained at a constant temperature and pressure, the equilibriunm condition for the coexistence of these two phases is that the specific Gibbs functions are equal Consider now a first-order phase change between the phase 1 and the phase 2. At the phase boundary, the equilibrium condition for the...
