a) From the phase diagram, estimate the vapor pressure of water at 350C. b) What phase is stable at room temperature and 1 atm pressure? c) If we increase the temperature from the compound at position X to 100C while holding the pressure constant, what is the state of water? d) If we take the compound at position X and increase the temperature to 200C while holding the pressure constant, what is the state of water? e) If we take the compound at position X and decrease the temperature to 10C and decrease the pressure to 0.006, what is the state of water? f) Is it ever possible for solid H2O to exist at a temperature above 20C ? g) Is it ever possible for gaseous H2O to exist at a temperature below 25C ? i) Does the sublimation point of ice increase or decrease with increasing pressure? h) Explain why pipes with water are in danger of bursting when the temperature drops below 0C
