Consider the phase diagram of CO2 given below to answer the following questions: р 73,8 bar 5,2 bar 1,013 bar 194,7 K 216,6 K (-78,5 °C) (-56,6 °C) T 304,1 K (+31,0 °C) a) Fill in the blanks and label the respective phases (i.e. s, I, g and sc). b) Name the lines I, II and III in the diagram. What does it mean when a point lies on one of these lines? What happens when your system crosses the lines I, II, and III? c) Which phase transition(s) can CO2 undergo at a pressure of 1 atm? Give the approximate transition temperature(s). d) Name the two indicated points at (5.2 bar / 216.6 K) and (73.8 bar/304.1 K). What are the characteristics of these specific points? e) State Gibbs phase rule and determine the number of degrees of freedom for i) a point within one of the phases, ii) a point on one of the lines and iii) at the specific point at (5.2 bar / 216.6 K).

You are high up in the mountains and boil water to makesome tea. However, when you drink your tea, it is not as hotas it should be. You try again and again, but the water is justnot hot enough to make a hot cup of tea. Which is the bestexplanation for this result? (a) High in the mountains, it isprobably very dry, and so the water is rapidly evaporatingfrom your cup and cooling it. (b) High in the mountains,it is probably very windy, and so the water is rapidly evaporatingfrom your cup and cooling it. (c) High in the mountains,the air pressure is significantly less than 1 atm, sothe boiling point of water is much lower than at sea level.(d) High in the mountains, the air pressure is significantlyless than 1 atm, so the boiling point of water is much higherthan at sea level.
