A system consisting of 0.20 mol of supercooled gaseous water (95°C, 1 bar) partially condenses to liquid water; the process is done adiabatically at constant pressure.         At equilibrium, what is the temperature of the system? How many moles of gaseous water have condensed? Calculate the entropy change for the process.
