11. List the order of phase changes that would occur based on the phase diagram of water under the following circumstances: critical point liquid Pressure (atm) 0.1- solid vapour (gas) triple point 0.0012 / 100 200 300 400 500 Temperature (K) 600 700 a. Water vapor originally at 200 atm and 150°C is slowly allowed to expand at a constant temperature until the final pressure is 0.005 atm. b. Water originally at 100.0°C and 0.50 atm is cooled at a...
If we have water vapor at 100 oC and 1.2 atm we should expect it to condense into liquid water as this is the most stable phase under those conditions (i.e. the boiling point of water should be higher than 100 oC at 1.2 atm ). This, in turn, should mean that the chemical potential of the water vapor should be larger than that of the liquid under those conditions. Estimate the difference in J mol-1 (no decimal places) when...
