Phase Diagram Practice Refer to the phase diagram below when answering the questions on this practice: 2.00 1.75 Critical point 1.50 Liquid 1.25 1.00 Solid ro batt 0.75 Gas 0.50 0.25 0.00 Temperature (degrées C) 1) Label the diagram with the words SOLID, LIQUID, GAS. 2) What is the temperature and pressure of the triple point? 890°C, 0.70 ATM 3) What temperature is the normal boiling point of this substance? 325°C 4) What temperature is the normal freezing point of this substance? 100°C 5) If I had a quantity of this substance at a pressure of 1.25 atm and a temperature of 300° C, what state of matter would the substance be in? Liquid If I lowered the pressure to 0.25 atm, what phase change would occur? vaporization or boiling 6) At what temperature do the gas and liquid phases become indistinguishable from each other? (critical point) 800°C 7) If I had a quantity of this substance at a pressure of 0.75 atm and a temperature of -100° C, what two phase changes would occur if I increased the temperature to 600° C? melting and vaporization Ravid At what temperatures would the two phase changes occur? 99°C and 150°C
